Indirect addressing means that QANF / ZANF points to a memory area where the
addresses of the source res. destination areas and the indicator word are stored. In this
context you may either define one area for data source, destination and indicator word
(IND = 5) or each, data source, data destination and the indicator word, get an area of
their own (IND = 6). The following table shows the possible QANF / ZANF parameters for
indirect parameterization:
QTYP/ZTYP IND = 5 IND = 6
Definition Indirect addressing for source or destination param-
eters and indicator word (ANZW). The source or
destination parameters and ANZW are stored in a
DB in a sequential order.
