摘要
本文是在完成了WANG-PC机的中西文COEOL语言编译系统研制工作后,对研制过程中的一个关键问题——执行器COBRUN·EXE中的CRT驱动程序工作原理及实现方法所做剖析的总结,文中从硬软件两个方面分析了该编译系统对在CRT中实现字符输入输出所采用的特殊机理和所具有的各种功能。这些分析和所得到的结果对最终实现整个编译系统,特别是执行器COBRUN的汉化将有直接和重要的影响。
This paper analyses the working principle and the methods of imple(?) menting CRT drive program in Runtime Executor of the WANG-PC COBOL. They are the key to the questions of implementing Chinese-West Langu(?) age compatible COBOL. The special mechanism and various functions of the characters I/O on CRT are introduced from both hardware and Software respe(?) cts.
