I have always wanted to use the .run executive command within
procedures. Seems strange that you can't. I tried using the
@routine.pro syntax but had problems.

You might find a work-around for this, but I would suggest
putting the system-dependent code inside your wrapper functions,
since that's more consistent with the purpose of using a
wrapper function in the first place. Or you might have a
"master" wrapper function that calls other "sub-" wrapper
functions according to the value of !VERSION.OS .

The second approach would have the same effect as your
previous attempt ... only the sub-wrapper that gets called would
be compiled.
