Quick, beginner MASM register question - DX:AX
- by Francisco P.
Hello, I am currently studying for an exam I'll have on x86 assembly.
I didn't have much luck googling for ":", too common of a punctuation mark :/
IDIV - Signed Integer Division
Usage: IDIV src
Modifies flags: (AF,CF,OF,PF,SF,ZF undefined)
Signed binary division of accumulator by source. If source is a
byte value, AX is divided by "src" and the quotient is stored in
AL and the remainder in AH. If source is a word value, DX:AX is
divided by "src", and the quotient is stored in AL and the
remainder in DX.
Taken from "Intel Opcodes and Mnemonics"
What does DX:AX mean?
Thanks a lot for your time :)
