HELP! I'M LOOKING FOR INFO .... RUSH! I WAS JUST GIVEN THE ASSIGNMENT BUT IT SHOULD HAVE BEEN DESIGNED YESTERDAY (TYPICAL) ! I have a design need where I must convert between EBCDIC to ASCII code and visa versa. The hardware I must interface to is an old IBM 360/50 hooked to an IBM 1052 console. I need to pick off the data stream from the interconnecting cables and convert the data from IBM EBCDIC code to standard ASCII code on a serial RS232 port. Does anyone out there know if "such-a-animal" exists? It could be a hardware or software or combination solution, I'm open for suggestions, before I have to design it from the beginning. If you can be of any help call me at (614)860-4455 or send by electronic mail to ...!cbosgd!cbsck!tks Thanks! Tom Snow - AT&TBL Columbus, Ohio

try the dd(1) program in UN*X, or a simple table lookup, depending on how your code is designed. Be carefull of sign extension when reading 8 bit characters with the hi bit set. Most computer handbooks/encyclopedias have both ASCII and EBCDIC tables in them if you have to roll your own. ZZ -- Richard Klappal UUCP: ..!ihnp4!chinet!uklpl!rlk | "Money is truthful.

I should like to point out that the information going over to the 1052 typer is more than likely not EBCDIC, but rather the classic Selectric typer "rotate/tilt" code. The 1052's that I had to deal with all required this rather strange code. And, while I can probably dig out some ancient manual with said codes and voltages, I really wonder if what you're proposing is feasible. Norm Crowfoot, RIT 716/244-5830 x 3574

(So you have to store reverse the ASCII in the 360 to send it.) --henry schaffer
