It depends on what we are talking about.
Under Unix (and Dos, and winslow) any program can return an integer 
value. The process sets the value, and the parent process retrieves it. 
In gambas you set the value with

	Application.Return = xxx	' <- integer value

if Charlie is not wrong.

You can test the exit code with "$?" in bash, and hProcess.Value in gambas.

But in this thread I saw you talked about file names; you can't return other data than a simple integer; if you need to return a string, or something else, you must find another way. The most easy one is to write to standard output or standard error, and read that stream from the parent process. Then one can also use some well-known file in /tmp (say, /tmp/my-program-data.tmp). There other methods too, but more complicated.

Doriano
