说明：  自行定义两个数据（字节或字均可，带符号数或无符号数均可），编程实现两个数的大小比较。若NUM1>NUM2，AL寄存器送字符﹥，并在屏幕上显示该字符；若NUM1<NUM2，AL寄存器送字符﹤，并在屏幕上显示该字符；若NUM1=NUM2，AL寄存器送字符﹦，并在屏幕上显示该字符。
(Two self-defined data (byte or word can be, the number of signed or unsigned may be), Programming size comparison of two numbers. If NUM1> NUM2, AL register to send characters> and displays the character on the screen If NUM1 <NUM2，AL寄存器送字符﹤，并在屏幕上显示该字符；若NUM1=NUM2，AL寄存器送字符﹦，并在屏幕上显示该字符。)
