请问lodsd,lodsw是什么意思

[wesen1111]

请问lodsd,lodsw是什么意思，有什么作用
例如：
while [esi].VirtualAddress
cld
lodsd ;eax = [esi].VirtualAddress
mov ebx,eax
lodsd ;eax = [esi].SizeOfBlock
不明白lodsd后面解释到底怎么来的

LODS - Load String (Byte, Word or Double)
Usage: LODS src
LODSB
LODSW
LODSD (386+)
Modifies flags: None
Transfers string element addressed by DS:SI (even if an operand is
supplied) to the accumulator. SI is incremented based on the size
of the operand or based on the instruction used. If the Direction
Flag is set SI is decremented, if the Direction Flag is clear SI

is incremented. Use with REP prefixes.
Clocks Size
Operands 808x 286 386 486 Bytes
src 12/16 5 5 5 1

AC LODS m8 Load byte at address DS:(E)SI into AL
AD LODS m16 Load word at address DS:(E)SI into AX
AD LODS m32 Load doubleword at address DS:(E)SI into EAX

AC LODSB Load byte at address DS:(E)SI into AL
AD LODSW Load word at address DS:(E)SI into AX
AD LODSD Load doubleword at address DS:(E)SI into EAX

俺翻译一下
lodsb,lodsw,lodsd,是串读取指令，功能是将数据段中的字节（sb），字（sw），双字（sd）读取至AL（字节），AX（字），EAX（双字）中。
