Mark Williams C compiler

Mark Williams C compiler

[Scott]

Hi,

I hope this is the right place to ask this. 

I have been running dosemu 1.0.0 (old, I know!) forever on this old
machine here at my office. I have several old programs which were
written years ago to be compiled with Mark Williams "Let's C"
compiler. They seem to compile fine under dosemu. 

Now I am fixing up a new machine to upgrade this one. I downloaded the
newest dosemu, with freedos. Seems to run just fine, however when I
try to compile anything with "Let's C" I get:

  Nope REP F3,CSP=0x00a5
  ERROR: general protection at 0x101218:f3

I definitely need to get this stuff migrated soon. Is the fault that I
am using freedos instead of a real dos? Perhaps I can find the old dos
disks and make a dedicated partition or drive for them in the new
machine. Can I just copy this old DOS off of the hard-drive and it
will run? I use DOS so rarely, I can't remember this stuff. But every
year (these are tax preparation programs I wrote for this office) I
need to kick my dos brain back in gear for a week or so to do
upgrades. I'm okay for this year, but I can hear this hard-drive
starting to go out (after only 12 years!) and so if anyone can point
me down the proper path, I would appreciate it.

I didn't found this compiler for download so I couldn't check, but...

I have never been fully success with freedos, so I suppose you should check 
other DOS first. There's a lot of bootdisk images available on the web - 
start with MS DOS 6.22.

BTW... is this compiler is really a must? Theres lot of other C compiler you 
could check (djgpp, turboc, pure c...?).

Maybe the original poster has some project written with that Compiler to
maintain as legacy...
