Does anyone know how to convert a file that is in EBCDIC format to ASCII format? Is there a command/program to do this under UNIX/ULTRIX ? If not, does anybody know of a public domain program to do the conversion? Thanks, !bob

The option conv=ascii converts EBCDIC to ASCII wereas conv=ebcdic converts ASCII to EBCDIC Bye, Thomas. -- *-----------------------------------------------------------------------------* Thomas Omerzu UUCP: ...!unido!quando!omerzu / omerzu@quando.uucp Quantum GmbH, Bitnet: UNIDO!quando!omerzu / omerzu%quando@UNIDO(.bitnet) Dortmund, Germany Internet: omerzu@quando.quantum.de

In article <1694@quando.quantum.de> omerzu@quando.quantum.de (Thomas Omerzu) suggests using `dd': > conv=ascii converts EBCDIC to ASCII Unfortunately, while there is only one ASCII (or two if you count the old non-standard version with arrows where [\]_ appear in modern ASCII), there are very many different (and incompatible) EBCDICs. Take any two pieces of IBM hardware that support more than the `basic' EBCDIC set (upper & lower case, digits, and a few special symbols) and they will not use the same table. Square brackets on one will turn into hats on another.% Backslashes will vanish. Some IBM equipment can even display characters it cannot generate! (I know of no instances of the reverse, which is not to say that they do not exist.) So, the first problem with EBCDIC to anything conversion is to figure out exactly which EBCDIC is being used. . . . ----- % Actually, I am not sure what usually maps to what, but the characters [] {} \ and ^ are the biggest trouble spots. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 405 2750) Domain: chris@cs.umd.edu Path: uunet!mimsy!chris

This is really easy to write in C, just declare a static array of 256 unsigned chars and initialize it with the numeric values of the ASCII characters. Make sure the array position corresponds to the EBCDIC value as you will use the EBCDIC value as the indice into the array, like so: /* etoa.c */ #include <stdio.h> typedef unsigned char byte; static byte ascii[256] = { initializers, go, here, }; main() { int c; while ((c = getchar()) != EOF) putchar(ascii[c]); } I can mail you both the ASCII and EBCDIC array declarations if you need them. -- Arthur W.

Is there a command/program to do this under UNIX/ULTRIX ? "dd" does this; RTFM. Unfortunately, there are multiple notions of EBCDIC encoding and the one that "dd" implements may not be 100% what you want, although it should be quite close.

Yes indeed. It's even worse. I think they also have country specific EBCDIC codes. I ran into this problem years ago with a System 34 here in Germany.

I have made a program to do conversion between about 60 character sets including 20 versions of EBCDIC.

> Before implementing this program, you might check to see if the options >available on the 'dd' command are suitable for the intented purposes. Unfortunately, ssome of the other suggestions didn't bother suggesting doing this check first. From the SunOS 4.0.3 DD(1) (but they all work this way, and the manuals should all say this): cbs is used only if ascii, unblock, ebcdic, ibm, or block conversion is specified. In the first two cases, cbs char- acters are placed into the conversion buffer, any specified character mapping is done, trailing blanks trimmed and NEW- LINE added before sending the line to the output. In the latter three cases, characters are read into the conversion buffer, and blanks added to make up an output record of size cbs. so that the "ascii" and "ebcdic" and "ibm" options are for converting between ASCII lines (NL at the end, UNIX lines) and EBCDIC *card images*. This may or may not be what the original poster wanted....
