Some time ago I noticed that z/OS Language Environment has support for both 
"FORTRAN IV" and "VS FORTRAN" (FORTRAN 77 standard), even though the latest 
Fortran compiler hasn't been enhanced since 1993 (??).  I've been learning 
modern Fortran (standards Fortran 90, 95, 03 and 08) using GNU Fortran and 
actually quite like it, but I can't imagine using anything prior to the 1990 
standard.  Anyway, I am curious if anyone uses Fortran on z/OS in their shop, 
and if so, why?

Is Pascal also still supported/used?  I don't see any mention of it in LE 
documentation.  Are there any other "legacy" MVS languages still in use (i.e., 
ones that haven't been updated in the last 30 years...)?  I've seen mention of 
APL2 on MVS, and maybe even Smalltalk?

Just wondering!
