PFSHOW | NOPFSHOW
Specifies that the PF keys be shown at the bottom of the screen. The default is
PFSHOW.

NOPFSHOW
Specifies that PF keys not be shown at the bottom of the screen.
RUNOPTS(’LE/370–runtime-options’)
Specifies a string containing LE/370 runtime options, which are passed to
LE/370 when the TSO/E OMVS command starts up, and to the initial login shell
program in the _CEE_RUNOPTS environment variable. These options are the
same as those passed to other LE/370 programs run from the TSO READY
prompt.
The options string can be from 1 to 1000 characters in length, and should
contain valid LE/370 runtime options. It should not contain options such as
POSIX(OFF), TRAP(OFF), TRAP(ON,NOSPIE), or MSGFILE(), or characters
such as slashes, unbalanced parentheses or quotes, or imbedded NULL
characters. Specifying such options or using these characters will cause
unpredictable problems when the TSO/E OMVS command runs.
If the RUNOPTS operand is omitted, OMVS uses the RUNOPTS string defined
in the BPXPRMxx SYS1.PARMLIB member that is active for the OMVS kernel.
If no RUNOPTS string was defined in BPXPRMxx, no LE/370 runtime options
are used when the TSO/E OMVS command starts up.
For more information, refer to z/OS Language Environment Programming Guide
which contains a discussion about restrictions on _CEE_RUNOPTS
environment variable setttings.
SESSIONS(n)
Specifies the initial number of sessions to be started. The default is 1, and the
allowed range is 1 to 100; most users will use two or three sessions.
Note: You can specify a number from 1 to 100 without getting a syntax error
on the command. Normally, you cannot start more than several sessions
before getting an error message. If you try to start too many sessions
(the limit depends on the size of your TSO/E address space), your
TSO/E user ID runs out of storage and various unpredictable errors may
occur. You may have to log off your TSO/E user ID before you can
continue.
SHAREAS | NOSHAREAS
Specifies whether to run the shell program in a separate address space. Both
OMVS and the shell will run in the TSO/E address space when OMVS is
invoked with the SHAREAS parameter.
