+ This function updates a form that has previously been registered with the HII

+
+ The form to update is specified by Handle, FormSetGuid, and FormId. Binary
+ comparisons of IFR opcodes are performed from the beginning of the form being
+ updated until an IFR opcode is found that exactly matches the first IFR opcode
+ specifed 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 beng 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 exatly 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
+ the matching start IFR opcode. If StartOpCcodeHandle only contains one
+ IFR instruction, then the result of ths operation will delete all of the IFR
+ opcodes between the start end matches.

+ @param[in] FormId The ID of the form to update.
+ @param[in] StartOpCodeHandle An OpCode Handle that contains the set of IFR
+ opcodes to be inserted or replaced in the form.

+ that marks the end of a replace operation in
