[net.lang.f77] 4.2-f77 vs SysV-f77

sah@mips.UUCP (Steve Hanson) (07/25/85)

What would be the reasons for selecting the Berkeley Fortran compiler
or the System V, Release 2 compiler if one had both available to them
and needed to port a large amount of Fortran code that wasn't developed
on either of them ? Does anyone know the strengths and weaknesses of
the two compilers and math libraries in terms of performance and
adherence to the Fortran standard? What's the reason(s) for weak 
performance?

Is it generally true that Fortran code developed on one of the compilers
will run unchanged on the other? Can a Berkeley Fortran compiler run
on System V system and can a System V compiler run on a Berkeley system 
without much porting trouble?

If there is enough response, I will post the them.
