Description

The main problem was the resolution of startOffset for that field that is not an overlay, next to another that is it. Considering this code:

     D A40_DS10A                      5    DIM(3)
     D  DS10A_FL1                     2    OVERLAY(A40_DS10A:01)
     D  DS10A_FL2                     3    OVERLAY(A40_DS10A:*NEXT)
     D A40_DS10B                      9    DIM(3)
     D  DS10B_FL1                     4    OVERLAY(A40_DS10B:01)
     D  DS10B_FL2                     5    OVERLAY(A40_DS10B:*NEXT)

the previous implementation attempted to resolve it by the endOffsetIncludingAllElement of previous field. In this case DS10A_FL2 that is an overlay. To fix the problem I put a searching of the first definition of field that is not an overlay.
