Re: help wanted

Hi Peter,

I see that Henk Salemink has sent you source code. If that doesn't
work out, let me know and I'll send it to you.

I was a PL/I programmer about 25 years ago. I'd be interested in
looking at your Web site if you'd post the URL here.

Being somewhat of a computer antiquarian, I just uploaded PLUM to my
modern Dorado 180 and tried to execute it. I got an error saying
INVALID ABSOLUTE ELEMENT - MAYBE OBSOLETE FORMAT - TRY REMAP which
tells me that the executable format is so old (absolute created in
1976) that it's no longer supported. Unisys 1100/2200 systems are
very good about maintaining backwards compatibility. I've got other
software of the same vintage where the executable still runs (e.g.,
@DOC from 1975!), so PLUM might have been built on a system that was
not new in 1976. When I have time (I wonder when that will be?), I'm
going to try to re-assemble and re-collect PLUM from the source code
and see if I can get it to work on my current system.

BTW, if memory serves, Unisys (Sperry Univac at the time) also had a
PL/I compiler for the 1100 Series system. I'm not sure when it was
released or how long it lived as a product.
