If you do not want anyone to use the program, it would be easier and wiser to exclude public use to the object:
wrkobj library/program *pgm. option 2 to edit authority, then change user *PUBLIC to *EXCLUDE.
or EDTOBJAUT library/program *pgm
or GRTOBJAUT OBJ(library/program) OBJTYPE(*PGM) USER(*PUBLIC) AUT(*EXCLUDE)
To stick to your request though, use the command to Change Object Auditing (CHGOBJAUD) for the program. Then you can view the audit log for all access to the program if that is what you want.
