Hello,
     Microsoft Fortran Version 5.00 (ver 4.0+, actually) has the C functions
'system' and spawnlp' buiilt in to is libraries (assumming you did not
require C compatability?).  These will give you what you need, The required
information is buried in Section 4.2.5 (page 86) of the Advanced Topics
book.  They also include a demonstration program DEMOEXEC.FOR that gives
examples on using these routines.  I'm not suprised that you could not
find this info, I knew about it from a upgrade flyer for Version 4.01
and I think that they should have placed this information with the other
additional procedures in the reference book.

Hope this helps you and anyone else that needs this info;

I don't work for Microsoft, I just use their product in this instance
