I'd be in favor of removing them unless the -V flag was set.

Most of our msi use is intended to be loaded w/ macro definitions in our st.cmd
file, so it's just annoying to see ",undefined" in files we've built up from templates
when we know we'll define those macros later.

We set the -V flag only for those few msi uses where the files need to have
all macros expanded.   For those cases it would still be helpful to see
the ",undefined" or ",recursive" warning text in the msi output file as we do now.

Cheers,

If there is a consensus that they are not useful I have a modification
that removes the ",undefined" error indicator from the output generated
by macLib (and hence the output from msi as long as the -V flag is used)
when it encounters a $(macro) that it doesn't have a value for. There is
also a ",recursive" marker for macros that are defined in a substitution
file using themselves.

As Bruce said, these markers don't change how a file is interpreted by
an IOC when they are present, but if you feed the output into some other
tool that doesn't understand them they might be annoying.

Please discuss here if you particularly like or dislike these markers.

Hi,

   Is there any other way to suppress or omit (,undefined) in the output
file by using MSI?

   Thanks,
