汇编语言ASCII码表是一种将字符映射为对应ASCII码的表格。在汇编语言中,常用的ASCII码指令包括:ADD、ADC、INC、AAA、DAA、SUB、SBB、DEC、NEC、CMP、AAS、DAS、MUL、IMUL、AAM、DIV、IDIV、AAD、CBW、CWD、CWDE和CDQ等。
下面是汇编语言ASCII码表的英文翻译:
ADD ----> add 加法指令
ADC ----> add with carry
INC ----> increase 1
AAA ----> ascii add with adjust
DAA ----> decimal add with adjust
SUB ----> subtract
SBB ----> subtract with borrow
DEC ----> decrease 1
NEC ----> negative
CMP ----> compare
AAS ----> ascii adjust on subtract
DAS ----> decimal adjust on subtract
MUL ----> multiplication
IMUL ----> integer multiplication
AAM ----> ascii adjust on multiplication
DIV ----> divide
IDIV ----> integer divide
AAD ----> ascii adjust on divide
CBW ----> change byte to word
CWD ----> change word to double word
CWDE ----> change word to double word with sign to EAX
CDQ ----> change double word to quadrate word
另外,还有拓展ASCII码表,用于输出256个字符的ASCII码表格。该表格的格式通常为25行,每行显示若干个字符及其对应的ASCII码值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
