Using the (extended) implicit form of the EXEC command z/OS TSO/E Command Reference SA32-0975-00 |
|||||||||||||||||||||||||||||
When using the implicit form of the EXEC command, TSO/E finds the REXX exec or CLIST as follows. Table 1 lists the search order of the user-, application-, and system-level libraries. Also shown are the ddnames associated with each library level. These ddnames can be allocated either dynamically by the ALLOCATE command or included as part of a logon procedure.
With the default settings that TSO/E provides, and before
an ALTLIB command is invoked, TSO/E searches the system EXEC library
(default ddname SYSEXEC) first, followed by the system CLIST library
(ddname SYSPROC). Note that your system programmer can change this
by
You can alter the default library search order by using
either the ALTLIB command or the EXECUTIL command.
Use ALTLIB DISPLAY to see which libraries are being searched for. The following example uses the implicit form of the EXEC command. It shows how the procedure is run. In this example, assume that the TSO/E prefix is ‘slk27’. |
