Is it possible to use the DDS keyword CHANGE at the record level on a subfile or subfile control? I coded it that way, but when I get back from the EXFMT, the indicator is not on. It does appear to work on non-subfile display file formats.
No. You have to read the sub-file records to determine if anything was changed in a sib-file. READC in RPG, READ SUBFILE NEXT MODIFIED in COBOL, _Rreadnc in C, and READ FILE() OPTIONS(RECORD() MODIFIED) in PL/1 will do it.
NOTE: You can use CHANGE on the sub-file control record to detect global changes to fields in the control record itself (such as subset or positioning fields).
