Return code MS DOS question

[Sudmill]

is an environmental variable set to the value of the last return code the cmd session received.
I am only asking so that my testing is made easier, so when my application returns a returncode (not directed), i can interrogate this return code onthe fly.

I know I could write a batch file to do this, but Im not sure how to do this on the fly.
Any ideas, as Im sure I read how to do this somewhere before!

Cheers

John.

Since cmd.exe is a DOS emulation program, all environment variables are inherited from NT itself.

You can set them within a session, but this will not be propagated to other sesions.

I hope this goes some way to answering your question.

Actually all I wanted was to print return code in the current session which I have now found;

ECHO %ERRORLEVEL%

But thanks anyway !
