I strongly recommend Language Systems FORTRAN for MPW.  I have had it
for about 1 1/2 years, and it's been a good performer.  It is very
VAX-compatible and very robust.  The current version is 1.2.1; version
2.0 (which should be out RSN) will have near 100% VAX compatibility
and a real optimizer.  Support and documentation are very good.  The
only downside is the expense; for many people, a $400-500 expense for
the compiler, MPW, assembler, and a debugger is no small potatoes.

MPW can take a while to learn -- but it's worth it!  Give me
MPW over any other programming environment (Mac, VAX, Unix, etc.)
any day!  MPW, if you're not familiar with it, has a top-notch editor,
a source code management system, most Unix tools, and an interface
that allows anything to be done either on the command line or with
the mouse (dialog boxes for all tools, compilers, etc. to select
options and files).  MPW supports C, C++, Pascal, Modula-2, and
Simula in addition to FORTRAN.  It allows portable mainframe programs
(such as most Unix C programs) to run with few or no modifications
as MPW tools.

LS FORTRAN will support LINPACK and EISPACK routines just fine.  In
addition, both NAG and IMSL provide subroutine libraries for use
with this compiler (NAG, and perhaps IMSL, used LS FORTRAN to
develop their Mac libraries).
