SAS Companion for the OS/390 Environment

Macro Statements

The following macro statements have OS/390-specific aspects:

is analogous to the KEYDEF command in the windowing environment. It enables you to define function keys. The form of this statement is

%KEYDEF <'>key-name<'> <'definition'>;

The number of keys available depends on your terminal. Most terminals that are used under the OS/390 operating environment have either 12 or 24 function keys. To define a key, specify the key-name (F1 through F24) of the key and the new definition.

If you omit the definition, SAS prints a message in the log showing the current definition of the key; otherwise, the key's definition is changed to whatever you specified.

%TSO

executes TSO commands during an interactive SAS session. It is similar to the TSO statement. (See TSO.) The %TSO statement enables you to execute TSO commands immediately. It places the operating environment return code in the automatic variable SYSRC. You can use the %TSO statement either inside or outside a macro. The form of the statement is

%TSO <command>;

You can use any TSO command or any sequence of macro operations that generate a TSO command. If you omit the command, your SAS session is suspended and your OS/390 session is placed in TSO submode. To return to the SAS session, enter either RETURN or END.

If you execute a %TSO statement on an operating environment other than OS/390, the statement is treated as a comment.

%SYSEXEC

executes TSO commands during an interactive SAS session. The form of the statement is

%SYSEXEC <command>;

Under OS/390, the %SYSEXEC statement works exactly like the %TSO statement. The two statements are different only if you transport your SAS program to a different operating environment. Because %SYSEXEC statements are recognized on multiple operating environments, each operating environment expects commands that are appropriate for that operating environment.
