I'll never forget Bill Munson's warnings at the 1980 USENIX conference. Munson ran 'TIG' - Telephone Industries Group, in Merrimack, NH - who job at DEC was helping their largest customer: AT&T. Us university types were screaming at Bill and team "When is DEC going to 'support' UNIX?" Bill got up an cautioned, 'Be careful what you wish/ask us to do. If we do support Unix, we will have to put Fortran, Cobol, and PL/1 on it -- which I don't think you really want.'

I'm not sure which languages did eventually get supported and on which versions of Ultrix. But once Paul's lk was released (and you can still find it in /bin on the base Ultrix distributions), you did indeed see a number of the languages move to Ultrix. I think for the Vax it was just VAX/11C, Fortran and Pascal. I think Ultrix11 may have gotten Fortran, but as I said; I don't remember. I do remember the TIG folks talking about a PL/1 project and a proposal for Cobol and RP/G because some of the Wall Street types wanted them, but I don't remember any of those getting released (that said, I was also not watching things Vaxen by that time). By the time I came back to Ultrix to do the MIPS 4000 stuff a few years later, tech languages offerings were different and the GEM compilers had come on the scene.

Another curious compiler at DEC was VAX Ultrix Fortran. DEC had
gotten a lot of push-back from the research community, who wanted to
use VAX and Ultrix but considered the f77 compiler inadequate and
wanted to use VAX Fortran, which only ran on VAX/VMS. There was a
rush project to port VAX Fortran to Ultrix. It was decided that the
quickest way to get a quality compiler to market was to have the VAX
Fortran compiler continue to emit VMS-format object files, and to
modify the VAX/VMS linker to accept a.out object files and to emit
a.out images. Four of us worked on the linker port. Two of us from
the VAX/VMS languages team did the linker mods and two engineers from
the Ultrix group wrote code to translate VMS debug information to Unix
stabs. The resulting linker was called lk. The VAX Fortran RTL was
also ported, and since we had a way to produce Unix executables from
VMS object files, it meant we didn't have to rewrite the RTL, which
was mainly in BLISS but also had modules in Fortran, VAX assembler,
and Pascal.
