Dynamic Access to Offsets and Lengths in Release 4.6A

Offsets/lengths specified dynamically enable a specific position to be accessed within a field or structure using values that are only known at runtime. This access type is available in Release 4.6A for all statements relating to fields.

Other versions: 7.31 | 7.40 | 7.54

Example

g+off2(len2) = f+off1(len1).

Starting with offset off2 in length len2, the field g is assigned the content of field f starting with offset off1 in length len2. If the two field lengths are not identical, the remaining positions are cut off or padded with initial values. The fields f and g must have the type X, C, N, D, or T. Structures are also allowed.
