Have you tried compiling a small DOS program with bcc and seeing what it
would interpret its parameters as?  It might be helpful if it printed one
argument per line, or somehow indicated where the break in the arguments

Also, IIRC from my DOS hacking days, assembly programs received the whole
parameter string at once, and had to parse it themselves, so it's possible
that you have found a bug in TLIB's argument parsing routine.
