Re: Stuck in unesacpe (Part 2) -- WEB400

Richard,

        I had already solved the x2c() issue another way. .(See begining of
part 2 thread).   The problem is that while the message is intact in the CGI
program that processes it, a copy is forwarded via a socket connection to a
FreedBSD (Unix) box for additional processing and that copy is NOT intact.
To prepare that transmission I obviously have to put the message back into
ASCII before writing it to the socket.. Since the xlate table looks right,
and the socket should be transparent I am not sure where the braces are
getting lost or what the issue is yet....

        By the way it's not just the [], also saw about 5 other characters
get corrupted, like the ^ and  ! and |.......

        Thks for your time.
        JMS...
