These combined conditions are valid:
Abbreviated Combined Relation Conditions
COBOL enables you to abbreviate a sequence of complex relation conditions. For
example, you can use
A NOT EQUAL B OR C
instead of having to use
(A NOT EQUAL B) OR (A NOT EQUAL C)
You can abbreviate any condition in a sequence except the first one by omitting either
of these:
•
The subject, for example:
A NOT EQUAL B OR NOT EQUAL C
•
The relational operator and the subject, for example:
A NOT EQUAL B OR C
The subject is the term to the left of the operator. For more information, see Usage
