RBF generates certain comment blocks in the report specification file. They are the width comment block, JoinDef comment block, and union select comment block. Comment blocks are visible when a report is archived or copied with the copyrep command.

Do not modify comment blocks in RBF reports. Changing a comment block can make the report unusable by RBF, sreport, and Report-Writer. If the report specification file has been archived, you can replace certain comment blocks with Report-Writer statements, if appropriate, as noted in the following subsections.
