- specified by StartOpCodeHandle. The following rules are used to determine if
- an insert, replace, or delete operation is performed:
-
- 1) If no matches are found, then NULL is returned.
- 2) If a match is found, and EndOpCodeHandle is NULL, then all of the IFR opcodes
- from StartOpCodeHandle except the first opcode are inserted immediately after
- the matching IFR opcode in the form to be updated.
- 3) If a match is found, and EndOpCodeHandle is not NULL, then a search is made
- from the matching IFR opcode until an IFR opcode exactly matches the first
- IFR opcode specified by EndOpCodeHandle. If no match is found for the first
- IFR opcode specified by EndOpCodeHandle, then NULL is returned. If a match
- is found, then all of the IFR opcodes between the start match and the end
- match are deleted from the form being updated and all of the IFR opcodes
- from StartOpCodeHandle except the first opcode are inserted immediately after
