I have used IBM's APPC/PC product to write a gateway application that talked to VTAM and CICS. APPC/PC is a (large 200K) TSR that has an assembler API to the APPC verbs. LU6.2 is designed for multi-tasking environments. APPC/PC forces you to write an "application subsystem" that loads and runs transaction programs, and helps with configuration issues. I implemented transaction programs as finite state machines with a single entry point that returned control to the subsystem dispatcher after each message exchange. There was only one EXE file. Be sure to order the programming guide from IBM with the product as they are sold seperately. What are xmit commands ? OS/2 EE communications manager supports LU6.2 and has a much friendlier API. -- Mike Zintel {uunet,ubc-cs}!van-bc!mdivax1!zintel
