简单运算和延时
[目的]　熟悉TASM、TLINK的操作，练习用简单的指令和伪指令编写完整的程序，并调试通过。
[设计要求]
1．　　在数据段建立以 NUMB 为首址，以 byte 为单位的数据区域，NUMB 和 NUMB+1单元分别为36H和18H, 再编写 .EXE 程序，求这两个数的差与商。
2．用 NOP 指令编一段完整的 .EXE 延时程序，循环 40000 次。
3．观察有关寄存器、存储单元和 FLAGS 的改变。(Simple operation and delay
[Objective] to be familiar with the operation of TASM and TLINK, and to write complete program with simple instruction and pseudo instruction, and debug through.
[design requirements]
1. in the data segment to establish the NUMB as the first site, byte as the unit of data region, NUMB and NUMB+1 units are 36H and 18H, and then write.EXE program, seeking the difference between the two numbers and quotient.
2. compile a complete.EXE delay program with NOP instruction, cycle 40000 times.
3. observe changes in registers, memory cells, and FLAGS.)
