Ordering functions not equals (==)
- ne(a, b)
- a <> b
ne(a, b) or a <> b results in a boolean data item indicating if the values of data item a are not equal to the corresponding values of data item b.
The comparison between two missing values (null == null) results in the value False.
Data items with Numeric, Point. string or bool value type
- Domain of the arguments must match or be void (literals or parameters can be compared to data items of any domain).
- Arguments must have matching:
1. attribute<bool> AneB (CDomain) := ne(A, B);
2. attribute<bool> AneB (CDomain) := A <> B;
