Pop-up Menus

[Brent L. Bates TAD/HRNAB ms294 x2601]

     I am tring to use the advanced menu formats from FORTRAN, but they don't
work.  The main problem I am having is when I try to use %F or %f in a
addtopup.  The functions either not called or the program bombs.  Has anyone
tried to use SGI's menus?  The people I have talked to here; have either given
up or didn't bother to try and wrote there own menu software.  I would like
to try SGI's.  Any suggestions?
