Passing Control to IKJADTAB

Your program can invoke the alternative library interface routine by using either:
  • The CALLTSSR macro instruction, specifying IKJADTB as the entry point name
  • The LINK macro instruction, specifying IKJADTAB as the entry point name.
However, you must first create the IKJADTAB parameter list and place its address into general register 1.

IKJADTAB must receive control in 31-bit addressing mode. The parameters you pass to IKJADTAB must be in the primary address space. This routine accepts input above or below 16 MB in virtual storage. Alternative library definition tables created by IKJADTAB reside above 16 MB in virtual storage.
