Code in these columns could be the result of expanding TAB characters in your source program, instead of standard TAB stops. If your source program contains TAB stops, convert them to spaces.
If your RM/COBOL program used the >>IMP MARGIN-R AFTER END OF RECORD directive for long source records, remove that directive from the source and use the Enterprise Developer SOURCEFORMAT"variable" directive. Note that source lines longer than 256 bytes are not supported and will be truncated with a message at compile-time.
RM/COBOL implementor defined directives >>IMP for source format, >>LISTING ON/OF and >>PAGE are not supported.
