How do I develop a HLLAPI application?
It is possible to program HLLAPI applications in any Microsoft supported language (C++, Visual Basic, etc.).
All 3270 emulators use the same HLLAPI function name with the same parameters: hllapi (&parm1, &parm2, &parm3, &parm4)
All 3270 emulators have different names for the name of the HLLAPI DLL and LIB file. The name of the PASSPORT HLLAPI DLL file is PASSHLL.DLL and the name of the LIB file is PASSHLL.LIB.
If a programmer already has access to HLLAPI documentation, they only need to do the following:
link the PASSHLL.LIB file into their application
load the PASSHLL.DLL file when their application loads
call the appropriate HLLAPI functions as they desire
