TSO modifiable control variables (CLISTs)
Your CLISTs can use the control variables to obtain such current information.
You do not have to define control variables. Control variables to which you can assign values are called modifiable control variables. The descriptions for this section are from the IBM publication, TSO Extensions Version 2: CLISTS.
The variables in this list are supplied by TSO and are available to all different CLIST types. You can modify the variable values.
Table 1. TSO modifiable control variables for CLISTs
| Variable | Description |
|---|---|
| &LASTCC | contains the most recent return code from the execution of the last TSO command or command procedure statement and indicates whether the command was successfully processed Use &IMFRC to check the return code of the TSO command. Note To check the return code from the most recently executed IMFEXEC statement, use &IMFCC. |
| &MAXCC | contains the highest return code from any TSO command or command procedure executed so far |
| &SYSASIS | ON specifies Control SYSASIS. OFF specifies Control NOSYSASIS. |
| &SYSCONLIST | ON specifies Control CONLIST. OFF specifies Control NOCONLIST. |
| &SYSDVAL | information entered from the terminal after a TERMIN or READ statement |
| &SYSFLUSH | ON specifies Control FLUSH. OFF specifies Control NOFLUSH. |
| &SYSLIST | ON specifies Control SYSLIST. OFF specifies Control NOSYSLIST. |
| &SYSMSG | ON specifies Control MSG. OFF specifies Control NOMSG. |
| &SYSOUTLINE | contains the number of lines of command output that were produced by a TSO command and points to the CLIST variables containing the output |
| &SYSOUTTRAP | contains the maximum number of lines of TSO command output to be saved |
| &SYSPROMPT | ON specifies Control PROMPT. OFF specifies Control NOPROMPT. |
| &SYSSCAN | contains the maximum number of times a that CLIST can rescue a line to evaluate variables The default is 16 times. The maximum value is +2,147,483,647. The minimum value is 0. |
| &SYSSYMLIST | ON specifies Control SYMLIST.OFF specifies Control NOSYMLIST. |
