1、十進(jìn)制與十六進(jìn)制互換說(shuō)明：程序運(yùn)行，選擇功能。按1鍵：十進(jìn)制轉(zhuǎn)換成十六進(jìn)制，鍵入值：0-255；按2鍵：十六進(jìn)制轉(zhuǎn)換成十進(jìn)制，鍵入值：0-ff；按q鍵：退出。代碼部分：stacksegmentstack'stack'dw100hdup(?)toplabelwordstackendsdatasegmentselectdb?decimaldb5dup(?)bufferdb100dup(?)keybufferdb100db?db100dup(?)string1db'press1:deciamaltoHexadecimal',0dh,0ah,'press2:Hexadecimaltodec
