For the initiated:

If you're wanting to dis-assemble Win-dos _executables_, make me a
_reasonable_ offer on SOURCER v6.55 with BIOS Pre-Processor, and ASMtool
v3.07, from V Communications, which I bought new in 1995.

SOURCER makes multiple passes through executabless and produces
assembly-like listings (with optional comments: eg, interrupts, types of
jumps), and ASMtool produces flow-charts from SOURCER results.

Why do this? Maintenance of undocumented code, virus research, solving
compatibility problems ...

I dunno about "latest upgrades". The products do what is claimed for them,
ie, dis-assemble Win-dos executables, and produce flow-charts.

Nisi? Okay, "Caveat emptor".
