Re: re: tn5250 connect problems

Scott,

Yeah, that does fix it.  I plan on re-writing parts of tn5250 to implement
a scripting language functionality so I can write automation scripts that
interface with the AS/400.  I am taking data out of M$ Word, parsing it,
and using tn5250 to do the inserts into the AS/400.... When I get it done
i'll pass it along.

Thanks for all your help Scott.
