Returning a variable from VFP6

[Paul Mulloni]

Is there a way to return or print a variable to dos environment from where
the vfp exe is called?
eg c:\> myprog.exe
Return -> "Hello World" for example.

Thanks,

Paul.

Not easily. There may be a 3rd party utility that can do this for you.
The problem (in the past, anyway) is that all .exe's inherit a *copy* of the
environment they run in. Even if you can alter it successfully, it reverts
to it's original, unaltered state when the .exe exits. If you are trying to
chain the results of a vfp run into a batch file, why not have the vfp app
write a flag file to indicate success. Then the batch file can detect the
outcome with if exist...
If this isn't what you're trying to do, post more information, maybe we
can still help.

Thanks for that info. I have started down that track of writing the output
to a file then check for the result in that file. This was my backup
stragery.

Thanks again.

Paul.
