The TSO command is similar
to the TSO (or X) statement, the TSO (or SYSTEM) CALL routine, the
TSO (or SYSTEM) function, and the %TSO (or %SYSEXEC) macro statement.
It accepts the following argument:
is a system command.
Under z/OS, “system command” includes TSO commands,
CLISTs, and REXX execs.
To submit a TSO command,
or to invoke a CLIST or a REXX exec, use the TSO
command form
of the command. You can use the TSO command from the command line
of any window. SAS executes the TSO command immediately.
Under
z/OS, TSO is an
alias for the X command. On other operating environments, the TSO
command has no effect, whereas the X command is always processed.
You can use the TSO
command to issue most TSO commands or to execute CLISTs or REXX execs.
However, you cannot issue the TSO commands LOGON and LOGOFF, and
you cannot execute CLISTs that include the TSO ATTN statement. Nor
can you issue authorized commands, such as some RACF commands. However,
you can use the TSOEXEC command to issue authorized commands, as in
this example:
You can also use the
TSO command to go into TSO submode from within a SAS session. To start
the submode, enter
TSO from the command
line without specifying a TSO command. When the command is executed,
SAS goes into TSO submode and prompts you for TSO commands. Any commands
that you enter in TSO submode are processed by TSO, not by the windowing
environment. They can be any length. However, if the command is longer
than one line, you must enter a TSO continuation symbol.
In addition, you can
use the TSO command to issue the following UNIX System Services shell
commands:
cd,
pwd,
and
umask. The shell command names
must be specified in lowercase.
To return to the SAS
session, enter
RETURN,
END,
or
EXIT. Any characters that follow the RETURN,
END, or EXIT subcommand are ignored. An END command that occurs within
a CLIST terminates the CLIST without ending the TSO submode.
Note: The TSO command processor
does not know when or if it is invoking an interactive windowing application.
To avoid problems with screen clearing, you might want to invoke
ISPF, IOF, or similar facilities directly. For example:
tso ispf
This
method works only if you invoked SAS from the TSO READY prompt. It
does not work if you were already in ISPF when you invoked your current
SAS session.
