Passing Control to IKJCAF

Issue the CALLTSSR macro instruction in your program's attention routine to pass control to IKJCAF.

You must invoke IKJCAF in 31-bit addressing mode, after setting its addressing mode in bit 0 of register 14. The parameters you pass to IKJCAF must be in the primary address space. IKJCAF returns control in 31-bit addressing mode.

The following example shows the assembler code you can use to invoke the CLIST attention facility:

*
  R1=PARMADDR                        *Address of the
                                     *parameter list
*
  CALLTSSR EP=IKJCAF                 *Passes control to the
*                                    *CLIST attention facility

Note: Any routine that uses the CALLTSSR macro instruction to invoke IKJCAF must include the CVT mapping macro (CVT), which is found in SYS1.MACLIB and the TSVT mapping macro (IKJTSVT), which is found in SYS1.MACLIB.
