I've been using Excel and VBscript to retreive and post information to
another program (Exceed's Hummingbird) When I start the script I use to
following to allow access to Hummingingbird;

Dim HostExplorer As Object
Dim tn3470 As Object


Set HostExplorer = CreateObject("HostExplorer") ' Initialize
HostExplorer Object
Set tn3270 = HostExplorer.Hosts(0) ' Set object for current session

I use this because it's what I was told to use. My question?

How do I know that HostExplorer is the name use to define the Object?

How do I determine the right name to use for another program to define it
for an Object?
