1、子程序及其调用,教学内容子程序指令的格式和用法,在程序中含有某些固定顺序或重复出现的区域时,这些顺序或区域可以作为子程序,存入存储器内,反复调用以简化程序.子程序以外的加工程序为主程序,子程序的嵌套,M98子程序调用M代码。指令格式：M98 PXXXX XXXX；（P_ L _)在这条指令中，P后为子程序调用的子程序号和次数，调用1次时可省略次数。XXXX-子程序号M99子程序结束。说明：主程序可以调用两重子程序，即主程序调用一个子程序，而子程序又可以调用另一个子程序。主程序也可以重复多次调用子程序。子程序与主程序结构的区别是：子程序结束代码用M99，而不是M30。,主程序N1234.N006
