HZSLPDWR function

Purpose: REXX persistent data write function for the check. This is the interface to the assembler HZSPWRIT macro. See HZSPWRIT macro — Write Check Persistent Data.

Invocation: CALL HZSLPDWR. HZSLPDWR uses REXX variables to accept input and to return output instead of through a "Call Pgm(Parm)" syntax. Both input and output variables for HZSLPDWR closely resemble the parameters of assembler service HZSPWRIT.
