Table 1 shows those TRACE options that GTF will not use in combination. If two or more options from the same row are specified, GTF uses the option that has the lower column number and ignores the other options. For example, if you specify both SYSP and PI (see row D), GTF uses SYSP (column 2) and ignores PI (column 5).
| Row | Columns | ||||
|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | |
| A | SYSM | SYSP | SYS | SSCHP | SSCH |
| B | SYSM | SYSP | SYS | IOP, IOXP | IO, IOX |
| C | SYSM | SYSP | SYS | SVCP | SVC |
| D | SYSM | SYSP | SYS | PIP | PI |
| E | SYSM | SYSP | SYS | EXT | |
| F | SYSM | SYSP | SYS | RR | |
| G | SYSM | SYSP | SYS | CSCH | |
| H | SYSM | SYSP | SYS | HSCH | |
| I | SYSM | SYSP | SYS | MSCH | |
| J | SYSM | SYSP | SYS | XSCH | |
| K | CCWP | CCW | |||
| L | USRP | USR | |||
If an installation chooses to specify either IO or IOP in addition to IOX or IOXP, they will receive IOX records for DASD and tape devices and IO records for all other devices.
