The precompiler seems very fussy regarding the null indicator definitions.
You can't declare the indicator array as anything but an array of type
SMALLINT, and the number of elements must exactly match the number of fields
in your FETCH.  Any discrepancy and the precompiler will reject the null map
with the SQL5011.  I use the "I" datatype out of habit nowadays, because the
"B" datatype will truncate large numbers.  It should work just fine as 4b 0.

For an example of how strict the precompiler is, this gives an SQL0511:
DRtnNullRaw       ds                  occurs(10)         
D NullMap                        5i 0 dim(9)             
D TblLibNull                     5i 0 overlay(NullMap:01)
D TblNameNull                    5i 0 overlay(NullMap:05)
D TblTypeNull                    5i 0 overlay(NullMap:09)
D TblTextNull                    5i 0 overlay(NullMap:13)
D ColNameNull                    5i 0 overlay(NullMap:17)
D ColTypeNull                    5i 0 overlay(NullMap:21)
D ColLenNull                     5i 0 overlay(NullMap:25)
D ColScaleNull                   5i 0 overlay(NullMap:29)
D ColTextNull                    5i 0 overlay(NullMap:33)

apparently because of the presence of any fields other than the array.

This works:
DRtnNullRaw       ds                  occurs(10)
D NullMap                        4b 0 dim(9)    

As for PTF's, try the latest database group ptfs: SF99103.  I am on V4R3M0,
cume 99054 (way back!)
