Help needed now!

When compiling the exchange I get the following error:

10.x(479): Error: Illegal char ASCII: (28)
10.x(479): Error: 'Illegal CHAR' not expected

What do those numbers '479' and '28' mean? Where can i look for this error. I have checked all the conditions and cannot find anything wrong. The ASCII file layout also is fine. Let me know please!!

baan is trying to compile a script for your exchange schema.
Please check line 479 in the script.
I'm not sure if the script will be already in the directory that you specified in the master data for the schema. If not have a look in $BSE/tmp
Could you also check $BSE/log for more details ?
