How can I give a value back to program that start me?
« on: November 03, 2009, 03:10:01 pm »
Hello,

how can I give a value back to program that start me? A simple string is enough or a errorlevel in pure FPC code.

Thank you very much...

Do you mean like this?

WriteLn('response');
or
WriteLn(StdErr,'error');

you can also assign a value the the ExitCode variable. This is the same as the DOS errorlevel
