==============================================================================
= Alpha Commands
==============================================================================

In this list of routines, text between '<' and '>' is a placeholder for a 
required parameter, text between '[' and ']' is a placeholder for an 
optional parameter, and the '|' signifies a choice of two or more 
alternatives.  A '+' signifies that the previous symbol can be present one 
or more times, while a '*" means zero or more times.  Some commands have no 
parameters, and are only expected to be called interactively.



The following are Alpha-specific tcl routines:

 abbrev <label> <string> [<mode>] - register a label for <string>. See 
'execAbbrev'.
 abortEm - aborts whatever is currently happening
 addAlphaChars <chars> - Add <chars> to the list of characters that internally 
  are caught by the 'isalnum' and 'isalpha' calls. Can be used to augment 
  the list of characters that the \w pattern in a regular expression 
  responds to. Use w/ care.
 addMenuItem [-m] [-l <meta-characters>] <menu name> <item name> - Convert
  item to menu form and add to specified menu. If '-m' specified, menu 
  form conversion not done. The '-l' option allows you to use menu meta 
  characters as text of menu items. If the '-l' option is used, the 
  <meta-characters> string is interpreted for menu item attributes, and 
  meta-characters in <item name> are included in the menu item text 
  literally. For example: 
  	addMenuItem -m -l "/B" "Hello/C" 
  would appear as the text "Hello/C" in the menu, and have "B" as its 
  command equivalent.
 addDef <var> <val> - Permanently save an association between the var 
  'var' and 'val'. 'addDef' and 'addArrDef' are now the sanctioned way to 
  save values between sessions. Also see 'removeDef' and 'removeArrDef'.
 addArrDef <var> <field> <val> - Permanently save an association between 
  the var var(field) and 'val'.
 AEBuild [<flags>] <app (name|creator)> <aesuite> <aeevent> [<event parameters>]*  -
  Build and send an apple-event. 'AEBuild' is apple's code of the same 
  name. Each "event parameter" is two parameters, a parameter type and 
  the data for the parameter. See the AEBuild doc for more details, 
  :Tcl:SystemCode:think.tcl for examples. The flags are '-r' (wait for reply), 
  '-q' (queue reply, in which case 'handleReply' (in appleEvents.tcl) is 
  called with the reply as a parameter, and '-t <timeout>' specifies the 
  timeout in ticks.
 alertnote message_string
  This command will display message_string in a standard Macintosh alert box.
 alphaHelp - display Alpha help.
 ascii (see bindings).
 askyesno [-c] prompt
  This command will display a Macintosh alert box with 'prompt' displayed
  with the push buttons Yes and No. The command will return the 
  string "yes" or "no". The '-c' flag specifies that a cancel button be 
  used as well.
 backSpace - delete selection, or a single char if no selection.
 backwardChar - moves insertion one char back
 backwardCharSelect - extends selection one char back
 backwardDeleteWord - deletes previous word
 backwardWord - moves insertion one word back
 balance - selects smallest set of parens, braces, or 
  brackets that encloses the current selection
 beep [-volume num] [-list | sndName]?
  where -volume and -list are switches, while num and sndName are variables.
  Ex:  beep -volume 3 "click in set 5"  play at volume 3 the sound named
  "click in set 5" in the Alpha's snd resource.
  Any sound stored in that resource can be used as well, so feel free to
  paste a sound (with ResEdit) in the snd resource to have it available.

  beginning of the buffer
 beginningLineSelect - extend selection to the 
  beginning of the line
 beginningOfBuffer - move insertion to the beginning 
  of the buffer
 beginningOfLine - move insertion to the beginning of 
  the line

  color. If specified, the input RGB value is used as the initial color on 
  the colorpicker.
 copy - copy region
 cp <fromName>+ <toName>
  This command will copy the file fromName and name the new file toName, 
  overwriting any existing file. This command copies both data forks, and 
  the Finder information. 
 createTagFile - searches all files in current file set 
  and saves the locations of any function declarations
  in a file called 'cTAGS'.
 createTMark <name> <pos> - create a temporary 'mark' 
  at location 'pos'. 
 currentPosition - displays current and total bytes.
 cut - deletes and saves region
 deleteChar - delete char AFTER cursor
 deleteMenuItem [-m] <menu name> <item name> - Convert item to menu form 
  and delete from specified menu. If '-m' specified, menu form conversion 
  not done. 
 deleteModeBindings <mode> - Delete all bindings for specified mode.

 dialog [<-w width>|<-h height>|<-b title l t r b>|<-c title val l t r b>|
			<-t text l t r b>|<-e text l t r b>|<-r text val l t r b>|
			<-p l t r b>]+ 
  Create and display a dialog.  '-w' and '-h' allow width and height of 
  dialog window to be set.  '-b', '-c', '-r', '-t', '-e' and '-p' allow 
  buttons, checkboxes, radio buttons, static text, editable text and gray 
  outlines to be created, respectively.  All control types (except gray 
  outlines) require specification of a title or text, together with left, 
  top, right, and bottom coordinates.  Checkboxes and radioboxes have an 
  additional parameter, the default value.  At least one button must be 
  specified.  The return value is a list containing resulting values for 
  all buttons, radioboxes, checkboxes, and editable textboxes (static text 
  is ignored).  Buttons have value '1' if chosen, '0' otherwise.  The 
  dialog box exits at the first button press.

 dirs - show current directory stack. See 'pushd' and 'popd'.
 display [-w <win>] <pos> - move pos's line to top of screen.
 displayMode <mode> - Up to four characters of the 'mode' string are 
  displayed in the status line at the bottom of a window.
 dosc [<-c 'sign' | -n appName>] [-k 'clas'] [-e 'evnt'] <-s string | -f fileName> [<-t timeout|-r>]
  Send an AppleEvent, by default class 'misc', event 'dosc'.
   -c 'sign' 
   		"sign" is a four-letter creator signature of a running application.
   -n appName
   		"appName" is the name of a running application.
   -k 'clas'
   		"clas" is a four-letter event class.
   -e 'evnt'
   		"evnt" is a four-letter event class.
   -s string
   		"string" is the text of a script to send to the other app.
   -f fileName
   		"fileName" is the complete or relative pathname of a file the other 
   		application should execute.
   -t timeout
   		"timeout" is the number of ticks Alpha should wait for a response. A 
   		timeout of "0" means wait forever.
   -r
   		Do not wait for reply.
   -q
   		Queue reply.
   		
   If neither of the '-c' and '-n' options is chosen, the PPC Browser is 
   used. Either '-s' or '-f' must be chosen. Thus, you can have "Alpha 
   5.02" and "Alpha 5.02 Copy" sending Apple events to each other, or they 
   can send events to a remote server such as Apple's ToolServer. 
   "$HOME:Tcl:UserCode:createStuffitArchive.tcl" contains examples of 
   controlling Stuffit Deluxe via this command.

  bypass the "Wrap" dialog for files with long rows.
 enableMenuItem <menuName> <item text> <on|off> - Either enable or 
  disable the menu item of user menu 'menuName' that has text '<item 
  text>'. Note that unless the menu is not only created, but also already

  definition
 float -m <menu> [<-h|-w|-l|-t|-M> <val>] [-n winname] [-z tag] -
  Takes a created menu (not necessarily in the menubar), and makes a 
  floating window out of it. Returns integer tag that is used to remove 
  the window. NOT DYNAMIC!  W/ no options returns all currently defined menus.
  Displayed w/ system floating window WDEF if system 7.5, plainDBox 
  otherwise. -h through -M change width, height, left margin, top margin, and

  Format is list of lists, each sublist consisting of file offset, color 
  index, and possibly a hypertext command.
 getfile [<prompt>] [<path>]
  This command will display an SFGetFile() and return the full path name of the 
  selected file, or an error if CANCEL button was selected.  An optional path 
  parameter specifies a default directory or file.
 getFileInfo <file> <arr> - Given a file name, creates an array called 
  'arr' in the current context, containing fields 'created', 'creator', 
  'modified', 'type', 'datalen', and 'resourcelen'. 'created' and 
  'modified' are in a form suitable for the command 'mtime'.
 getGeometry [win] - return a TCL list containing the left 
  edge of the current window, the top, the width, and height.
 getline <prompt> <default>
  This command will display a Macintosh alert box with prompt displayed, a

 getNamedMarks [-w <win>] [-n] - 
  return list of all permanent marks in open files. Each
  element of a list describes one mark as a sublist of the mark's name, 
  the complete pathname of the mark's file, the position of the first 
  character in the first line displayed, the current position, and the 
  end of the selection if text is hilited, or the current position again 
  if there is no hilited section. '-w' allows window name to be applied 
  as filter, '-n' means only names will be returned.
 getPathName - prompt the user with an SFGetFile dialog and return 
  complete pathname.
 getPos [-w <win>] - return the current insertion point
 getScrap - returns system TEXT scrap.
 getSelect - return the currently selected text, if 
  any.
 getText [-w <win>] <pos1> <pos2> - return the text between 'pos1' 
  and 'pos2'. '-w' can be used to specify a window.
 getTMarks - Return a list of temporary marks. Each item of the returned 
  list is a sublist containing the mark name, the complete pathname of the 
  mark, and the start and finish of the selection named by the mark. The 
  following is an example of the result: 

    {{temp1 External:file.c 1312 1315} {temp2 Internal:it.h 111 111}} 

 getWinInfo [-w <win>] <arr> - Creates an array in current context 
  containing info about either the current or a specified window. Array 
  has fields 'state', 'platform', 'read-only', 'tabsize', 'split', 
  'linesdisp' (num lines that can be seen in the window), 'currline' 
  (first line displayed), and 'dirty'.
 glob [-i] [-t <TYPE>] [-c <CRTR>]
  The original glob provided by the UNIX version of tcl was not quite 
  adequate for the more complex Macintosh file system. Issues such as 
  invisible file handling, Finder type and creator filtering, and space 
  handling in file names. Release 6 of tcl has dealt with the original 
  problem with spaces in filenames, but the following options are provided 
  to deal with additional Macintosh issues. 

Anyway, the new glob now takes several options. They are:
	-i	This option causes glob to list invisible files also.
	-t TYPE	This option causes glob to only list file with the 
		indicated Finder file typeTYPE. This option may be 
		used with the -c option.
	-c CRTR	This option causes glob to only list file with the 
		indicated Finder file creatorCRTR. This option may 
		be used with the -t option.
		Also note that the original glob would skip dot files
		(i.e., file names the begin with a period) 
		in the listing, unless the pattern began with a period.
		Tickle extends this concept one step further on the
		Macintosh, and skips spot files (i.e., file names that 
		begin with ''), unless the pattern starts with a spot.
 goto <pos> - goto the position 'pos'.
 gotoMark - goto named mark, use 'mark' in macros.
 gotoTMark <name> - goto the temporary mark 'name'.
 icon [-f <winName>] [-c|-o|-t|-q] [-g <h> <v>] - Having to do w/ 
  iconifying windows. '-c' means close (iconify) window, '-o' open, '-t' 
  toggle open/close, '-q' returns either a '1' for an iconified window or a 
  '0' for an uniconified window, and '-g' moves the icon to horizontal 
  position <h> and vertical position 'v'. Options are executed as they 
  are parsed, so the '-f' option, if present, should always be first. 
 icURL <URL> - passes arg to Internet Config, if present. Error if not 
  present. 
 icGetPref [<-t <type>] <pref name> - Gets preference from 
  Internet Config. '-t' allows type to be set, '0' returns a string 
  (default), '1' returns a path name, commonly used for helper apps. A 
  <pref name> of 'all' returns all valid preferences.
 icOpen - Opens Internet Config
 insertAscii - prompts for an ASCII code and inserts
  into text.
 insertColorEscape <pos> <color ind> [hypertext func] - Create a color 
  or style "point" for documentation purposes. Look at the file 
  "docColors.tcl" for examples. The hypertext func is only used when the 
  "point" is underline. See 'getColors' for info about the current file.
 insertFile - prompts for a file name and inserts the
  corresponding file into the current window. Not
  undoable.
 insertMenu <name> - insert the previously created user menu 'name' into 
  the menuBar. 
 insertPathName - present the user w/ a SFGetFIle dialog 
  and paste the complete path-name of the chosen file
  into the current window
 insertText [-w <win name>] <text>* - Insert 'text' at the current 
  insertion point. Mark is unchanged.
 insertToTop - make the line that the insertion point 
  is on the first line shown, and display the current 
  line number along w/ the total number of lines in file
 isearch - incremental search: searches w/o a dialog,
  searches as you type the search pattern. Does not do
  regular expression searches. 'matchWords' 
  automatically set to false.
 iterationCount - allows actions to be repeated many times. "control-u 44 
  =" inserts 44 '='s into current window.  Also can be used to execute any 
  function or macro (including the keyboard macro) many times.  Defaults to 
  4.
 keyAscii - insert ascii representation (in decimal)
  of the keydown event, plus a modifier string, if 
  necessary.
 keyCode - insert the key code along w/ a string 
  representing and modifiers into the current window.
  Can be used to create bindings in 'Alphabits'.
 killLine - kill text from insertion point to the end 
  of the line. If the line has no text, delete the line 
  and move succeeding lines up one.
 killWindow - kill current window
 largestPrefix <list> - Returns the longest prefix contained in all 
  strings of 'list'.
 launch -f <name> - launch the named app into the background. Note that 
  for some yet unexplained reason, some applications (MicroSoft Word) 
  won't launch completely in the background. 'launch'ing such 
  applications won't insert the application into any system menu that 
  specifies running applications (although "About the Finder..." will 
  list it. The only way to get to such an app is through Alpha's 
  'switchTo', after which the application will finish launching. The '-f' 
  option gets around this by launching the application in the foreground 
  instead.
 lineStart <pos> - return the position of the start of
  the line 'pos' is on.
 listpick [-p <prompt>] [-l] [-L <def list>] <list>
  This command will display a dialog with the list displayed in a List Manager 
  list. If the user presses the Cancel button, an empty string is returned. If 
  the user selects the Open button, or double clicks an item in the list, that 
  item will be returned. If '-l' is specified, than the return is a list of 
  items.
 lookAt [-w <name>] <pos> - return the 'pos'th character of the 
  current file, or the file named by <name> if the '-w' option is specified.
 markHilite - This is the 'Hilite' from the 'Edit'
  menu. If there is a currently hilited selection, the 
  selection is unhilited, leaving the mark and the 
  insertion point around the old selection. If there 
  is not a selection, the region between the insertion 
  point and the mark is selected.
 markMenuItem [-m] <menuName> <item text> <on|off> [<mark char>] - Either mark or unmark
  the menu item of user menu 'menuName' that has text '<item text>'. 
  Note that unless the menu is not only created, but also already
  inserted, this command has no effect. 
 matchBrace - moves the insertion point to the 
  character that matches the character after the current 
  insertion point
 matchIt <brace char> <pos> [<limit>] - Return pos of matching brace. Recognizes 
  parenthesis, square brackets, and curly braces. Optional third argument 
  specifies how many characters to search.
 minPos - returns the first position in the current window.  This will
  normally be '0', but for future compatibility should not be so assumed.
 maxPos [-w <win>] - returns the position of the last character in the front
  window.
 Menu [-s] [-n <name>] [-i <num] [-m] [-M <mode>] [-p <procname>] <list of menu items> - 
  Defines a new menu named 'name' (if provided w/ '-n' option). The menu is not 
  yet inserted into the menubar. The menu commands may be nested for 
  heirarchical menus, see 'AlphaBits.tcl' for examples. Alpha massages the 
  function names to make them look better in the menus. 
  '-c'			Ignore any menu meta-chars. Can also be done on a per-item basis 
  				by appending an ampersand ('&') to the end of an item.
  '-s'			Use system menu definition proc (faster).
  '-n <num>'    Resource id of icon suite to use for menu title. 'ics#' 
                is the only resource that is really necessary.
  '-n <name>'	Name the menu. Not necessary for submenus.
  '-m'			No menu form. If not supplied, each menu item is split into 
  				words at each capitalized letter.
  '-p <name>' 	The tcl proc named by 'name' is called w/ the menu's name
  				and the item's contents when the item is chosen.
  '-M <mode>'	Specifies that any bindings created by the menu are 
  				specific to a given mode. This is important because mode-specific
  				bindings over-ride global bindings.
 message <string> - prints 'string' on the status line.
 mkdir <name> - creates a directory (folder) named 
  'name' in the current directory.
 mousePos - Returns list <row,col> of mouse position, if the mouse is 
  currently over the active window. Otherwise, return error (catch w/ 
  'catch').
 moveInsertionHere [-last] - move the insertion point to the 
  first (or last) line displayed
 moveFile <fromName> <toName>
  This command will move the file fromName to toName, overwriting any 
  existing file. The move can not be made across volume (disk drives) 
  boundaries. 
 moveWin [win name] <left> <top> - moves current or specified window. 
  The window name can be "StatusWin".
 mtime <time> [long|short|abbrev]
  Returns a date and time string using the Macintosh International Utilities. The 
  long/short/abbrev specification corresponds to the date. These are the following 
  formats:
	short		3/16/92 9:20:46 PM
	abbrev	Mon, Mar 16, 1992 9:20:49 PM
	long		Monday, March 16, 1992 9:20:43 PM
  The returned value actually is in the form of a list. To get text as 
  above, run the result through 'join', as in "join [mtime [now] short]".
 nameFromAppl '<app sig>' - Interrogates the desktop database for the first 
  existing app that has the desired signature. <app sig> is four chars 
  inside single quotes.
 new [-g <l> <t> <w> <h>] [-n <name>] - opens an untitled window. Can optionally 
  provide left and top coordinates, plus width and height. All or none.
 nextLine - move insertion point to next line
 nextLineSelect - extend selection to the next line
 nextLineStart <pos> - return the position of the start 
  of the next line after position 'pos'.

 now
  Returns the current time as Macintosh seconds. This is the number of seconds that 
  have elapsed since Midnight Jan 1, 1904.
 oneSpace - converts whitespace surrounding insertion
  into a single space.
 openLine - insert a new line following the current 
  one and move the insertion point to it
 otherPane - If window is split, select the other pane.
 pageBack - display prev screenful, move the
  insertion point if 'moveInsertion' enabled
 pageForward - display next screenful, move the
  insertion point if 'moveInsertion' enabled

  or 'copy'
 performSearch  [options] <pattern> <pos> - as for 'search' but also
  selects the range of characters which are found, and ensures Alpha's
  internal state is consistent for following replace/replaceAll/...
  commands.
 pos::math <pos> ?+/-? ?offset? ...  returns that position which is
  given by moving the given number of characters backwards or forwards
  in the current window.  Any number of offset arguments may be given,
  with or without spaces separating the arguments.  For future compatibility
  pos::math should be used in preference to numerical addition: positions
  cannot be assumed to be simple integers.
 pos::compare <pos1> <comparison> <pos2> returns 1 or 0 depending on
  whether the given comparison is true or not.  Valid comparisons are
  ==, !=, <, >, <=, >= etc.  For future compatibility, pos::compare
  should be used in preference to a direct, numerical comparison.
 popd - Pop top dir off dir stack and 'cd' to it.
 posToRowCol <pos> - converts from absolute position to row, col.
 prefixChar - used to further modify the next keystroke 
  combination, in the same manner as using the shift key 
  in the next keystroke
 previousLine - move insertion point to the previous 
  line
 prevLineSelect - extend selection to the previous line

  sublist contain a file-name, an application signature, the application 
  memory size, and the number of ticks the application has been active.
 prompt <prompt> <default> [<name> <menu item>*] - prompt dialog to 
  the user with a prompt string and a default value. The prompt dialog can 
  optionally include a popup menu specified by 'name' and the succeeding 
  strings. Selection of the popup menu items inserts the item text into the 
  editable dialog item. 'Prompt' returns the value of the editable item. 
  If the 'Cancel' button is selected, the tcl returns an error and your 
  script will be stopped unless you execute the command from 'catch'.
 pushd [<dir>] - If 'dir' specified, push current folder into directory 
    stack and 'cd' to dir. Otherwise, swap current dir w/ top of dir stack.
 putfile <prompt> <original>
  This command will display an SFPutFile() and return the full path name of the 
  selected file, or an empty string if CANCEL button was selected. Original is the
