[comp.dcom.lans] PC/HOST connectivity/data passing/HLLAPI/HELP ME!!!

Hello World!

I would like to be running an interactive high-level language
application on an IBM pc and have the added ability to be 
connected to a host(DEC,IBM,UNISYS, etc.), flip-flopping back    
and forth from application to application (hot-key?).

Questions:
       
      1.   what do I need in terms of hardware or software
           to be able to have concurrent sessions?

      2.   how can I pass data back and forth between
           applications (in both directions)?

      3.   what is HLLAPI and how can I use it to accomplish this?

      4.   is there a terminal emulation package available
           to do this?

This is what I need to accomplish:

    -  application A (running on the host) makes a request to
       application B (running on the PC).
    
    -  application B searches a database on the hard drive and
       returns some data to application A as its response.


I hope that this is not pie-in-the-sky and that someone out there
has a solution for me.  By the way, a high level language solution
would be preferred.     thanx everybody.
