Which definitely is a good thing in this case. Since most systems don't
have a C compiler anyway, the first compiler have to get down there
someway, and MACRO-11 is the only language you *know* exist.
I'm soon done with a cleanup of DECUS-C by the way. I've tried to collect
all the different versions I can find, and incorporated my own fixes as
well. This version will support I/D space correctly in RSX (which no other
version except my in-house hacks have done), will have a working profiler
again, and also supports RMS and DAP. Fun fun...
I'm testing it right now, and most things looks like they are working like
However, if someone have plenty of time, and an RSTS/E or RT-11 system
around, I'd sure appreciate some help. I've tried to keep those parts
up-to-date as well, but I cannot test, or fix broken things.
This compiler have been a mess for many years now... About time it got
Oh. And I don't know if Allan Baldwin (sp?) have some extra hacks in for
