Entering subcommands

Enter a subcommand as directed by the syntax diagrams. See Syntax conventions for more information.

Entering subcommands in IPCS line mode
Enter a subcommand at the IPCS prompt. For example:
```
IPCS
ANALYZE CONTENTION
```
Entering subcommands from an IPCS batch job
After the batch job has established an IPCS session, you can enter subcommands as you do from IPCS line mode. The following example shows how to enter a subcommand from the JCL or TSO/E job stream:
```
//SYSTSIN  DD *
IPCS
ANALYZE CONTENTION
/*
```
Entering subcommands from the IPCS dialog
There are two ways to enter subcommands from the IPCS dialog:
- Choose option 4 (COMMAND) and enter the subcommand on the command line:
```
===> ANALYZE CONTENTION
```
- Use the IPCS primary command to prefix the subcommand invocation from any command or option line of the IPCS dialog. For example:
```
COMMAND  ===> IPCS ANALYZE CONTENTION
```
