Giving back a Value

[Nimos]

how can I set what a proc gives back after ending?

e.g.

set something [some.proc here]

how can i choose what [some.proc] is?

To control what you want a procedure to return, use the [return] command. Example:

Code: Select all

proc whatever {a b c} {
 return "returns a string"
}

this will return a string containing "returns a string." Anything after the return statement is ignored.
