Not, trying to discourage anyone from messing with simh and one of the old
UNIX systems - looking at the past. But to be honest at this stage of the
game there is nothing in EFL that I know of that modern Fortran can not
do. And if you want to see how the world has progressed since F4, and you
have a Mac, Linux or Windows box -- the entire Intel compiler suite,
including their Fortran 2018 compatible system can be downloaded for free
-- Intel OneAPI HPC Toolkit Download
This is the compiler many (most) supercomputer codes use - why is a good
COFF discussion ;-)
For the youngsters that never saw it, is a piece of F4 code [the Intel
compiler can still gork it BTW], which we call the 'Eklund Test' as Dave
Eklund was Mr. Fixed format for both DEC and Intel starting in the early
1970s until he retired 5 years ago [note Dave did not write this - came
from Europe but is now part of the Intel compiler test suite].
C This FORTRAN program may be compiled and run on a Norsk Data
C computer running SINTRAN and the FTN compiler. It uses only
C FORTRAN reserved words, and contains just one numerical
C constant, in a character string (a format specifier). When
C you run it, it prints a well known mathematical construct...
C Even FORTRAN is a block structured programming language:
