The diagram below shows both output to SYSOUT by the system file manager and output rerouted to the S variable streams SYSINF and SYSMSG. The combination of the SYSINF and SYSMSG streams is referred to as SYSVAR.
Command and program output to S variable streams SYSINF and SYSMSG or to SYSOUT
SYSINF
The S variable stream SYSINF contains the structured output of (SHOW) commands and programs. See the manual “Commands” [3] for more details on the output formats.
SYSMSG
The S variable stream SYSMSG contains the structured output of guaranteed messages. See the manual “MSGMAKER” [21] for more details on message output in S variables.
SYSOUT
The output stream SYSOUT typically contains all outputs from command servers and utilities. The output is edited for screen display.
