The following commonly used commands ignore overrides entirely:
| ADDLFM | DSPFD |
| ADDPFM | DSPFFD |
| ALCOBJ | DSPJRN |
| APYJRNCHG | EDTOBJAUT |
| CHGOBJOWN | EDTDLOAUT |
| CHGPTR | ENDJRNPF |
| CHGSBSD | GRTOBJAUT |
| CHGXXXF (all change file commands) | INZPFM |
| CLRPFM | MOVOBJ |
| CLRSAVF | RGZPFM |
| CPYIGCTBL | RMVJRNCHG |
| CRTDKTF | RMVM |
| CRTDUPOBJ | RNMOBJ |
| CRTAUTHLR | RTVMBRD |
| CRTSBSD | RVKOBJAUT |
| CRTTAPF | SBMDBJOB |
| DLCOBJ | SIGNOFF |
| DLTF | STRDBRDR |
| DLTAUTHLR | STRJRNPF |
| DSPDBR |
|
| Note: | Save operations and restore operations ignore all file overrides that are related to the respective media (tape, diskette, save file). |
The system does not apply overrides to any system files that are opened as part of an end-of-routing step or end-of-job processing. For example, you cannot specify overrides for the job log file. In some cases, when you need to override something in a system file, you may be able to change it through a command other than an override command. For example, to change the output queue for a job log, the output queue could be changed before sign-off using the OUTQ parameter on the Change Job (CHGJOB) command to specify the name of the output queue for the job. If the printer file for the job log contains the value *JOB for the output queue, the output queue is the one that is specified for the job.
The following commands allow overrides for the SRCFILE and SRCMBR
parameters only:
| CRTCMD | CRTPRTF |
| CRTICFF | CRTSRCPF |
| CRTDSPF | CRTTBL |
| CRTLF | CRTPF |
| CRTXXXPGM |
|
| (All create program commands. These commands also use overrides to determine which file will be opened by a compiled program. See Applying overrides when compiling a program for more information.) | |
The following command allows overrides for the TOFILE, MBR, SEQONLY,
LVLCHK, and INHWRT parameters:
| OPNQRYF |
|
The following commands allow overrides, but do not allow changing the MBR
to *ALL:
| CPYFRMPCD | CPYTOPCD |
The following commands do not allow overrides to affect the display files that they use. Overrides to the printer files they use should not change the file type or the file name. Some restrictions are placed on changes that may be made to printer files used by these commands, but the system can not guarantee that all combinations of possible specifications will produce an acceptable report.
