I tried RUNning both a valid and an invalid program, and in both cases
IoErr() return the same value ( 0xC4 ).  So, what was the indication
you referred to??

I found CommandLineInterface in dosextens.h, but found no other reference
to it.  Please tell me how I can locate this structure from within a
program.   Please include a code fragment for searching the path if
you can afford the time.

Thats what I thought.   Thanks for the tip, too.
