Ah oh, something bad happened

The most likley cause of an error is a poorly formatted copybook. The copybook must be formatted just like it is for the COBOL compiler. Copybook statements must be between columns 6 and 72, inclusive.

Below is the actual error message, if it says something like "expecting: number88, number not88" then it is a badly formatted copybook. If you are receiving a different error or you can't make your copybook work, contact us via email at
