:00423992 8B453C                  mov eax, dword ptr [ebp+3C]
:00423995 BE01000000              mov esi, 00000001
:0042399A 3BC8                    cmp ecx, eax
:0042399C 743A                    je 004239D8
:0042399E 894D3C                  mov dword ptr [ebp+3C], ecx
:004239A1 8BCD                    mov ecx, ebp
:004239A3 E8F8FCFFFF              call 004236A0
:004239A8 6A00                    push 00000000

                                  |
:004239AA 6828664400              push 00446628
:004239AF E89CA70000              call 0042E150
