Thanks & Regards,

  1. You can search the web as easily as I can.
  2. I already told you you could use iconv() from libc. And bigearsbilly already told you you could use the dd utility. But, as I have repeatedly told you those COBOL data formats are binary; not EBCDIC.

You could always use lookup tables here is a simple shell script to generate two "DAT" files into the "/tmp/" folder and are 256 bytes in size...

You just need to compare byte for byte and convert accordingly or join the two files together and convert bytes 0 to 255 against bytes 256 to 511 and vice-versa.

A simple lookup library of your own...

Needless to say this is in its simplest form but is a starter...
Code:
#!/bin/bash
> /tmp/ASCII.DAT
> /tmp/EBCDIC.DAT
character=0
char=""
for character in {0..255}
do
	char=`printf '\\\\x'"%02x" $character`
	printf "$char" >> /tmp/ASCII.DAT
done
dd if=/tmp/ASCII.DAT of=/tmp/EBCDIC.DAT conv=ebcdic
ls -l /tmp/*.DAT
hexdump -C /tmp/ASCII.DAT
hexdump -C /tmp/EBCDIC.DAT
echo ""
echo "You now have two very, VERY basic, 256 byte lookup tables to access."
echo "1) /tmp/ASCII.DAT..."
echo "2) /tmp/EBCDIC.DAT..."
echo ""
exit 0

Results on OSX 10.7.5, default bash terminal...

You now have two very, VERY basic, 256 byte lookup tables to access.
1) /tmp/ASCII.DAT...
2) /tmp/EBCDIC.DAT...

Wisecracker, he doesn't actually want EBCDIC, he's just parroting the term... And hasn't answered any of our questions enough for us to have the ability to help him.

This might help with a translation. It was written for COBOL, but could be adapted for other languages as well http://home.comcast.net/~wporter211/...ascebc.cob.txt
