Working with nulls in RPGLE

With nulls, you can still fetch into a data structure. Simply specify the data structure followed by another data structure (array) that will hold the values of the null indicators. Define same number of elements in this array as there are fields in the data structure -- in the case of the example below, this is 12.

Example:

* CustomerRow -- an externally described data structure based on SQL view allCusts
d customerRow e ds extname(allCusts) qualified

* Null indicator arrays
d customerNIArr s 5i 0 dim(12)

EXEC SQL
FETCH custListCursor INTO :customerRow :customerNIArr;
