Using the Visual Basic Interface

To use the Visual Basic interface:

1. Include the HLLCALLS.BAS file in your project.
2. Before calling any EHLLAPI functions, call EHLLAPIQuerySessions. This determines which, if any, 3270 sessions are available. The returned string contains the short names of the available sessions.

All EHLLAPI functions return the EHLLAPI return code, as described in the EHLLAPI Programming Guide.
