Using the ALTLIB command

z/OS TSO/E CLISTs
SA32-0978-00

The ALTLIB command offers several functions, which you specify using the following operands:
ACTIVATE
allows implicit execution of CLISTs in a library or libraries on the specified level(s), in the order specified.
DEACTIVATE
excludes the specified level(s) from the search order.
DISPLAY
displays the current order in which CLIST libraries are searched for implicit execution.
RESET
resets searching to the system level only, for CLISTs and REXX execs.
For complete information about the syntax of the ALTLIB command, see z/OS TSO/E Command Reference.
Note:
  1. With ALTLIB, data sets concatenated to each of the levels can have differing characteristics (logical record length and record format), but the data sets within the same level must have the same characteristics.
  2. At the application and system levels, ALTLIB uses the virtual lookaside facility (VLF) to provide potential increases in library search speed.
