VALUELISTFROM attribute
The VALUELISTFROM attribute specifies an unsubscripted structure reference whose elements all have the VALUE attribute and which should be used to define a VALUELIST for the current declaration.
Given
dcl 1 a, 2 b fixed bin value(31), 2 c fixed bin value(28), 2 d fixed bin value(31);
dcl x fixed bin valuelistfrom a;
x
would then have the attribute VALUELIST(31, 28, 31).
