forcing C++ to talk to PComm

;) Hello, I was hoping to get help with a C++ situation/headache.
I would like to be able to write C programs that can utilize my mainframe sessions at my work. The actual session program is called PCOMM (Personal Communications) I've written partial programs in Visual Basic for Apps, and VB6 where I'd been told to code: "Dim PCOMMSession" and "autECLOIAWait As Object" and then "autECLOIAWait.SetConnectionByName(SessionChoice)" Later I would set variable "SessionChoice" equal to A, B, C, or D. Those being my four individual mainframe session choices.
This enabled interaction/ communication with the session, ie queries, and database info retrieval between my GUI program and the session itself. Please help if you know of a way that this would be possible using C++ programs.
Thanks very much,
CooperSan.
