In mid 80's I worked at Microrim for a short time. There was an effort to port R:Base (in Fortran) to Unix (especially Xenix). There was a Fortune Systems 32:16 machine running For:Pro (v7). It had EFL. I vaguely recall a discussion about going the Fortran->EFL->(might be easier to port to)->C route. I was there to help, but was a greenhorn and way in over my head.

Hi.

EFL was definitely a part of BSD Unix.  But I don't see it in the V7
stuff in the TUHS archives.  When did it first appear?  Was it part
of 32V and I should look there?

It is definitely in the V8 and V10 stuff.

Did anyone actually use it?  I have the feeling that ratfor had already
caught on and spread far, and that it met people's needs, and so
EFL didn't really catch on that much, even though it provided more
features on top of Fortran.

Thanks,
