[开源] PLC梯形图转指令表的算法源代码

今晚确实很纠结的，七点多回家，项目经理打电话过来，明后天由于公司电力网络维护故休假两天，杯具！

 

更杯具的：到了九点多，又一电话敲过来，明后天XXO正常上班......

 

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////

本源码来自ourdev论坛，当初自己就是看这套代码，一直从第一行"骂"到最后一行，得狠狠地bs这个不带任何注释的作者，虽然“开源”的精神值得学习.....

注释没有加完，走马观花一番，关键是两个Compile函数需要花点时间研究，有兴趣的看看！
