Parameters

SPOOL=: Specifies the address of a list (in the form generated by the IATYSPL mapping macro) defining the set of table entries to be written.
LENGTH=: Specifies the length of each entry in the table. This length field must be supplied to the ITWRITE routine, either by use of this parameter, by an assembled value in the spool list, or by storing the value in the length field before this macro is issued.
ADDR=: Specifies the address of the entry to be written. This address field must be supplied to the ITWRITE routine, either by use of this parameter, by an assembled value in the spool list, or by storing the value in the address field before this macro is issued.
NORMAL=: This parameter specifies that after the macro processing routine executes, the issuing program can resume execution at an instruction other than the instruction that immediately follows the macro.
