PC*MILER Multi-Version Switch uses multiple .INI files. There is a primary pcmmv.INI, and each instance of PC*MILER|TCP/IP uses its own pcmserve.INI in that version's ...\Tcpip folder. 

Pcmmv.ini is used to locate the various instances of PC*MILER|TCP/IP. Values specified in pcmserve.INI will only be used if they are not specified by the calling application. 

NOTE:  Maintain case sensitivity - when editing your pcmmv.ini do not alter ‘PCMiler’.
