一套GPP的POST运行，至少有几个文件支撑，请具体说明。
GPP需要至少两个文件，分别是demo.def, demo.dex，一般安装之后还有一个demo.exf文件，这个文件不起实际作用，是编译成DEF之前的过程文件。目录在\\\\var\\post目录下。
题2：
一套IMS的POST运行，至少有几个文件支撑，请具体说明。
IMS需要一个文件，如\\\\var\\ims\\imspost\\prjfiles\\fanuc0.prj，
另外还有一个相关的文件很重要，如三轴立式的机床是\\\\var\\ims\\imspost\\mchfiles\\vertical.mch，当然还有\\var\\ims\\imspost\\deffiles\\cimatron.def，它指定了APT的特殊格式
希望可以多交流，将这个问题谈得深一点，如： 1.在GPP中程序头加入刀具信息等； 2.在GPP中指定代码文件的放置目录； 3.在GPP中指定不使用圆弧插补； 4.在IMS中检验APT程序；
5.在IMS中指定使用刀尖作为对刀点；
matthews兄和sirhc兄都说到点子上了，看来大伙儿对POST还是很有基础的。我把这两个问题的答案综合一下，讲解就从这个突破口开始。 题1：
一套GPP的POST运行，至少有2个文件支撑，分别为*.DEX和*.DEF，IT版在\\var\\post目录下，E版在CIM_E\\IT\\var\\post目录下。请注意我说的“至少”，因为还有一个*.CMD文件起着关键作用，比如指定G代码的存放目录，连接外挂程序，删除多余的伴随文件等。*.CMD文件是否要起作用，由*.DEF文件中的一个控制项来决定。如何设置，以后会讲。而*.EXF文件虽然在POST运行时不需要，但POST设置全靠它，因此不能抛在一边。
*.EXF文件是GPP型POST的源代码，能手工编辑，有可读性。
*.DEX文件是GPP型POST的执行代码，类似二进制文件，很难手工编辑，没可读性。它由*.EXF文件通过编译产生。
*.DEF文件是GPP型POST的数据输出格式控制文件。 题2：
一套IMS的POST运行，至少有4个文件支撑，在\\dat下的3个APT.*文件和\\var\\ims\\IMSPOST\\PRJFILES下的1个*.prj文件，这里的APT.CMD文件就起到了连接作用。而搞IMS，一般搞*.prj文件就行了，通常设置数据输出格式。没有GPP型POST支撑，IMS是不行的。
先到这里，下贴继续。有不对处请兄弟们指正。
我首先向大家说声：I AM SORRY，因我前段时间有事，发贴没心思，请兄弟们原谅！现继续我的瞎掰。 （1）
介绍几个跟POST有关的编译器。
cimitX\\BIN\\下的DFEXF.EXE是把*.EXF编译成*.DEX的程序。激活该程序后，会出现一个DOS窗，输入EXF型文件名（不要含扩展名EXF），即可生成DEX型文件。同C语言编译器一样，若EXF型文件有问题，编译器会显出错误的语句。你可按提示修改EXF型文件直到编译成功。DFEXF.EXE的快捷方式在IT的MAIN MENU下NC栏的第6个，即附图中第6个菜单。
生成DEF文件的程序CIM一般是不提供的，但CIM提供了DEF文件样本，即DEMO.DEF，我们可利用样本搞出不同的DEF文件来。cimitX\\BIN\\下的DFSTRD.EXE是配置*.DEF文件的程序。激活该程序后，会出现一个DOS窗，选择样本后就能进行配置，完成后另取一个文件名保存退出。配置DEF文件时DFSTRD。EXE要加参数：“P” DFSTRD.EXE的快捷方式在IT的MAIN MENU下NC栏的第5个，即附图中第5个菜单。
DFEXF.EXE和DFSTRD.EXE的默认目录是cimitX\\var\\post。 编译器具体使用在以后会提到。IMS的编译器明天讲。
错误处请兄弟们指正，不胜感谢！！！
不好意思，让兄弟们久等，我这人向来虎头蛇尾，兄弟们多担待。 （2） IMS
的编译器是
cimitX\\VAR\\IMS\\IMSPOST下的IMSPOSTW.EXE，它的默认目录为
cimitX\\VAR\\IMS\\IMSPOST\\PRJFILES，它能生成*.LIB文件。而LIB型文件也是类似二进制文件，只有通过IMSPOSTW.EXE才能看懂。搞IMS就是用熟IMSPOSTW.EXE。
IMS的执行器为PEXEC95.EXE。LIB型文件其实是PEXEC95.EXE运行时的配置文件。 下面讲一点IMS的运行过程。
CIM的默认POST为GPP，要使用IMS，必须加一个启动参数： “-IPOST”。
cimitX\\BIN下有一个POSTPR.DLL的扩展。当在CIM的环境中按下POST选项后，POSTPR.DLL被激活了，若它查到有参数： “IPOST“，便会到cimitX\\DAT下去执行APT（一个GPP型的），而APT活完，APT.CMD文件就活了，这个文件没有什么，只有一个意思，调用APT新生成的print0.txt文件，而print0.txt文件的内容就是去执行PEXEC95.EXE，即IMS。这就是有人所谓的CIM和IMS：”无缝集成“。兄弟们想想这缝隙有多大，APT的3个文件若有一个稍不行，IMS就不能活了。比如我将APT.CMD移到别的目录，IMS会翘辫子。因此，对CIM来说，IMS是外挂，不是集成。

先讲GPP，在讲之前，发一张GPP的系统变量表，以后会用到，这很重要。具体的解释我后面会举例，对英文感冒的兄弟不要怕。
