从键盘输入两个常数，求其最大公约数，并以常数形式输出-the greatest common divsion

this program is find the gcd of two number in 8086 microprocessor

1) it is code which gives lcm and gcd of 2 numbers. 2) to check if a number satisfies 2 out of 5 condition. 3) to check if the number is odd or even. 4) to square a given number. 5) to find number of 0s and 1s in a given binary number.

通过输入的控制，比较两个数的大小，再求取两个数的最大公约数-By the input control, comparison of two numbers, size, and then calculate the greatest common divisor of two numbers
