汇编程序

1.1编写一程序，作BCD数的四则运算，在程序中设置非压缩BCD数X，从键盘输入一位十进制数Y。将X+Y、X－Y、X＊Y及X/Y（不考虑余数）分别送ANS＿A，ANS＿S，ANS＿M及ANS＿D变量。

1.2编写一程序，实现两个三字节无符号数DATA1和DATA2的相加，结果送四字节变量ANS。

-Assembler program to prepare a 1.1 for the number of BCD arithmetic, the procedure set up in non-compressed BCD number X, from the keyboard input of a decimal number of Y. Will be X+ Y, X-Y, X* Y and X/Y (not considering more than a few) were sent to ANS_A, ANS_S, ANS_M and ANS_D variables. 1.2 to prepare a program to achieve two three-byte unsigned number of DATA1 and DATA2 sum, the results sent to four-byte variable ANS.
