In SDF-mode, if the parser encounters a repeated pattern of alternate-names (comment-card names), it will attempt to render them into an instance of a repeated group definition. IBM SDFII allows users to specify group definitions on a DEFINE STRUCTURE panel, such that they are not fully enumerated in the resulting BMS. Therefore, the BMS parser will make a best-effort to render these into a group, so that an appropriate copybook can be generated. This is not fail-safe, however, and the preferred method is to ensure that group member fields are prefixed with a comment of the form * groupname(grp-occ).fieldname.
- System Action:
- The system attempts to render the repeated pattern of fields into a repeated group instance.
- Resolution:
- Consider explicitly defining the group members with comments of the form * groupname(grpocc).fieldname.
