Hi Scott,
This is cool. Thanks for all the effort. Would you be able to send me a
copy of the source to the program so I can reproduce it?
By the way, I was unable to send mail to [EMAIL PROTECTED] It
bounced.
To all:
What do you think the best way to handle theses non-printable characters
are? I can easily copy the behavior of the real terminal if thats the
best solution.
Mike

Subject: Re: Another assertion failed error...
Hi Mike,
I wrote a program that displays a 1-byte field containing the EBCDIC
values from 0-255 (decimal). I tried this same program under RUMBA 2000
under Windows 98, tn5250-0.15.8 under FreeBSD (probably not the current
one from CVS, this one is a few weeks old), and also on an IBM terminal
(3179-2).
Neither RUMBA nor the terminal ever actually "crashed", tho I did achieve
some strange results with them. tn5250, as you know, does an assertion
failed on some of the values :)
The attached file is in text format, with UNIX-style newlines. It tells
you what happened with each byte value.
Here's an explanation for the results I listed in the attached file:
--------------------------------------------------------------------
Displays Blank = just a blank character is displayed.
Displays Block = a reverse-image blank, looks like a solid block
Displays Dup Char = on 5250 terminals, there is a character that means
that the dup key was pressed. It looks like an asterisk
with a horizontal line above it. When Mr. Felice
implemented the dup key under tn5250, he chose to use
a "block" instead, so the weird character didnt need to
be reproduced :)
Displays Garbage = some misc character that didnt matter much to me was
displayed :)
Screen Is Messed Up = the screen displays, but not all of the data is
where its supposed to be.
Locks = Screen came up blank, and I had to kill the session and restart :)
RNQ1251 = The program that I wrote to display the characters crashes, with
This IBM error message number. You can do a:
DSPMSGD RNQ1251 MSGF(QRNXMSG)
on the AS/400 to see what it means. I could answer this
message with a C to get back to my command prompt...
Hope you find this useful.
