Length of control level not consistent between record types or groups.
30
Cause . . . . . : Control fields are specified but the length of a control level (the sum of the lengths of the control fields at that level) for a record type or Field-Record-Relation group does not match the first definition of that control level.
Recovery . . . : Specify control fields whose lengths at each control level (L1-L9) are consistent. Compile again.
