proleap parse issue - Microfocus Dialect

[chrisfw]

Hello, I am experiencing issues attempting to parse the attached COBOL program (using the Microfocus dialect). The parser reports the errors below although the program compiles with no errors in Microfocus COBOL (both Server Express and Visual COBOL). Any information you can provide would be greatly appreciated.

Thanks,

Chris Whelan

Hi Chris! If you have a look at the underlying Cobol.g4 grammar, you will find the definition of the fileControlClause as follows in antLR: fileControlClause : assignClause | reserveClause | organizationClause | paddingCharacterClause | recordDelimiterClause | accessModeClause | recordKeyClause | alternateRecordKeyClause | fileStatusClause | passwordClause | relativeKeyClause

Obviously the "LOCK MODE CLAUSE" has not yet been implemented in the grammar. Thats also the reason for the parsing errors like "line 56:15 extraneous input 'LOCK' expecting {SELECT, DOT_FS}" For the time being I could only recommend you to comment out these LOCK Clauses in your Cobol program. rgds, Reinhard

Thank you for following up Reinhard. Is there anything planned in the project roadmap to enhance the grammar implementation with this and other unimplemented Microfocus features?

Hello Chris,

correct, support for Microfocus dialect is limited in the current version.

We are evaluating to add support for Microfocus, as this was the top requested feature in 2018! However, we have to take into account time and budget constraints, so we have to do this further development of the open-source components as a by-product of a billable project setup.

Best regards Ulrich

Good to hear there may be additional support for Microfocus coming in 2019. Thanks Ulrich - Happy New Year!
