Cannot parse a COBOL source

There are typically two reasons why a COBOL source cannot be parsed by RainCode:

• RainCode can only parse a COBOL source code without the leading and trailing characters put at fixed places for numbering or version control purposes. If the source file cannot be parsed, you must check whether the FirstUsableColumn and LastUsableColumn configuration variables have been set to proper values to match the layout of your source code.
• Due to the very large number of COBOL dialects and extensions in daily use, despite extensive tests, it is still possible that a given construct cannot be parsed by RainCode. Please reduce the offending source file until it cannot be reduced any further, and send it to us for analysis.
• If RainCode is integrated in a compilation chain before the compiler, it might be possible that an error is reported because there actually is an error. In such cases, please ensure that the source file which is not recognized by RainCode can be successfully compiled before looking any further.
