| red477 06. Dec 2006 | a questioin, is this a mistake or intentional? 00401A27 > AC LODS BYTE PTR [ESI] 00401A28 . 0FCB BSWAP EBX 00401A2A . 8A1C31 MOV BL,BYTE PTR [ECX+ESI];alway the same char!!!??? ... 00401A42 . 49 DEC ECX 00401A43 .^75 E2 JNZ SHORT cm.00401A27 at the commented line, the ecx is decreased but the esi has been increased by the instruction lodsb, so... If it is intentional, I am sorry for bothering. |
