TASKLIB data sets

The TASKLIB data set concatenation defines the run-time libraries for IRXJCL and their order. Any number of run-time libraries may be specified. A TASKLIB definition is used by the Enterprise Extensions Dependency Build to create the proper search order for the required IRXJCL program and any program the REXX exec calls.

A program can allocate one or more data sets to a TASKLIB concatenation. Data sets concatenated to TASKLIB are searched for after JPA but before any specified STEPLIB or JOBLIB. Modules loaded by unauthorized tasks that are found in TASKLIB must be brought into private area virtual storage before they can run. Modules that have previously been loaded in common area virtual storage (LPA modules or those loaded by an authorized program into CSA) must be loaded into common area virtual storage before they can run.

• Use the Add... button to add a data set to the concatenation:
  
• Use the Edit... button to update a data set in the concatenation:
  
• Use the Remove button to delete a data set from the concatenation.
• Use the Up and Down buttons to adjust the order of the concatenation.
