Confusion factor ;-)  We were using DSOM (Distributed SOM) on that one 
contract and I was looking to use it on another project for a different 
contract so I bought some version of Watcom that made a big deal out of 
DirectToSOM.  I'd have to go digging through the CD stack to find the 
version that had it but that would take a while - I'm a packrat when it 
comes to keeping old software around so the CD stack is (literally) several 
feet high.

My point was really that DSOM implementation drove a lot of improvement in 
the base SOM code hence the access we had to code.

You've got my curiosity up now.  I'll look and see if I can sort out the 
various Watcom releases.  I know the DirectToSOM functionality disappeared 
before the openWatcom era, likely because of license issues, but I'm fairly 
certain that at least one Watcom release included it because I tried to use 
it - with less than stellar results.

To give you a feeling for the search task: my office here at home has nearly 
50 feet of shelves containing just commercial software releases.  I even 
keep a couple of 8" floppy drives hooked up to read some of it.  One old 
machine has 8", 5.25", and 3.5" floppy drives installed plus a punch card 
reader.  I keep saying that I'm going to copy all that over to DVD but....
