Description
Specifies the system options.
Valid settings of SYSOPT are (options can be summed):
| Hex setting | Decimal setting | Meaning |
|---|---|---|
| X'80' | 128 | Write to audit trail and/or journal. |
| X'40' | 64 | Force an ABEND without a dump at termination when the return code is not zero. |
| X'20' | 32 | Include RK lines in the audit trail and/or the journal. |
| X'10' | 16 | Require login. |
| X'08' | 8 | Perform DISCONNECT during logout (not effective for terminals connected to Model 204 through CRAM). |
| X'04' | 4 | Execute Model 204 data definition commands within a particular run of Model 204 only through the File Management facility of Dictionary. |
| X'02' | 2 | Open CCAGRP for use of permanent file groups. |
| X'01' | 1 | Open CCASYS during initialization |
Setting option 4 restricts the use of Model 204 data definition commands within a particular Model 204 run. When the SYSOPT value includes option 4, the following commands can be executed only through the File Management facility of Dictionary/204:
| Commands restricted by option 4 | |
|---|---|
| CREATE FILE | SECURE FILE |
| INITIALIZE | DESECURE FILE |
| DEFINE FIELD | INCREASE |
| REDEFINE | DECREASE |
| DELETE FIELD | RESET |
| RENAME FIELD | |
The RESET option also restricts the resetting of any resettable file parameters except FISTAT. The following resettable file parameters are restricted:
| Command restriction by the RESET option | |
|---|---|
| BRESERVE | PRCLDEF |
| DRESERVE | ADDLVL |
| FOPT | READLVL |
| FRCVOPT | SELLVL |
| OPENCTL | UPDTLVL |
| PRIVDEF | VERIFY |
SYSOPT cannot be reset by the system manager.
