Turtle and Observer Command

let `[:variable value]`

Declares `variable` as a local variable and assigns `value` to it. All local variables must have names which begin with a colon. You may declare more than one variable in a let statement (ie. `let [:variable1 value1 :variable2 value2]`. Variables are declared in the order they appear in the let statement. See the Variables page for more information on local variables.

Variables defined in a let are visible from the let (outside the body of the let) to the end of the procedure

Examples:
let [:myvar 6] declares a local variable `:myvar` and assigns its value to 6.
