在光栅显示器原理样机研制阶段,我们采用了IBMPC/XT个人计算机作为GS(光栅)机的调试控制台.它方便用户可以直接在PC/XT上使用高级语言编制应用画面程序,可节省大量的软件开发周期.高级语言为了同IBM个人计算机的DOS或BIOS通讯,调用宏汇编是非常有用的.本文所述的宏汇编接口程序,为用FOR TRAN语言编制的GS画面程序与GS系统程序的接口,
In the development phase of Raster Prototype prototype, we used IBMPC / XT personal computer as debugging console of GS (raster machine), which is convenient for user to use high-level language for application screen program directly on PC / XT, which can save a lot of software Development cycle. High level language In order to communicate with DOS or BIOS of IBM personal computer, it is very useful to call the macro assembler.The macro assembly interface program described in this article is an interface between GS picture program and GS system program compiled by FOR TRAN language,
