I don't know what your shop standards are in the applications area, but for audit and traceability reasons EVERY file in our shop always gets at least a header record with origin information (i.e., what program/application wrote it and on what date at what time) and frequently also a trailer record with a record count and termination time. That kind of standardization would solve your problem immediately, unless the program in the job is vendor code for which you do not have source.
An all-JCL solution would be to use DISP=(NEW,PASS) for the GDG "creation" step and then an IEBGENER step with the GDG as SYSUT2 with DISP=(MOD,CATLG) and SYSUT1 of DUMMY. You might also need RECFM, LRECL and BLKSIZE on the SYSUT1 DUMMY to get it to work cleanly.
