IBM DOS/VS COBOL and ACUCOBOL-GT ignore the following clause in a file description entry statement:
VALUE OF value-pair-1 {value-pair-2} ...
Each value-pair is of the form
data-name-1 IS {data-name-2 } {literal-1 }
You may put a VALUE OF clause into a file description entry, but only when the compiler is in the IBM DOS/VS compatibility mode.
