   DON'T say none, Lattice C on the PC gives argv[0] as the program name
 and complete path it was executed under.  This is what inspired me to
ask the question about a TP inplemention in the first place.

  Since then I have found that the the program's name can be found at
$0:143d on my PC running DOS 3.?  but on other machines its at a slightly
different address.  I assume this data is part of a table but I don't know
were or how to find the starting address of this table.  If anyone has a
handle on what I'm talking about, I would greatly appreciate your help.
