/* BIT SHIFTING Here's my Problem, I want to make a 6bit register out of a 8bit register and retain the data that was shifted in the next register, then make that register 6bit, and so on... Basicly making 3 bytes into 4bytes(with the info shifted from the other 3 bytes). Example, 14h 0Fh A8h 00010100 00001111 10101000 25h 00h 5Eh 48h 00000101 00000000 00111110 00101000 (editorial note (RLH): The real values are 05h 00h 3Eh 28h 00000101 00000000 00111110 00101000 ) (UUENCODE, if you havn't guessed already) the best I can think of is UUEncode db 0014h, 000Fh, 00A8h LEA ESI, UUEncode MOV EAX, [ESI] SHR EAX, 2 The Problem I run into is, each Register is Indivdualy Shifted over 2 bits, dumping the shifted info instead of moving it to the next register. EX: 00000101 00000011 00101010 I'm new to the concept of Bit Shifting.. Thanks In Advance.
