Need help to understand fields

[IamNewbee]

Hi Guys, I have a piece of code which can be used to connect excel with mainframe application.
Below is the code which works perfectly:
Get the main system object
Dim Sessions As Object
Dim System As Object
Set System = CreateObject("EXTRA.System") ' Gets the system object
If (System Is Nothing) Then
MsgBox "Could not create the EXTRA System object. Stopping macro playback."
Stop
End If
Set Sessions = System.Sessions
If (Sessions Is Nothing) Then
MsgBox "Could not create the Sessions collection object. Stopping macro playback."
Stop
End If
'--------------------------------------------------------------------------------
' Set the default wait timeout value
g_HostSettleTime = 300 ' milliseconds
OldSystemTimeout& = System.TimeoutValue
If (g_HostSettleTime > OldSystemTimeout) Then
System.TimeoutValue = g_HostSettleTime
End If
' Get the necessary Session Object
Dim Sess0 As Object
Set Sess0 = System.ActiveSession
If (Sess0 Is Nothing) Then
MsgBox "Could not create the Session object. Stopping macro playback."
Stop
End If
If Not Sess0.Visible Then Sess0.Visible = True
Sess0.Screen.WaitHostQuiet (g_HostSettleTime)


I understand the overall working of this code but would like to study each fields(like g_HostSettleTime,OldSystemTimeout etc) deeply. I tried to search for the explanation on the internet but no luck. Could anyone share links/documents where these fields are explained properly. I would appreciate if someone can explain it to me if you don't have any material.

Have you tried contacting Rocket Software to see if they have some documentation?

I tried to search in their website, couldn't find anything.

What you're showing is almost the identical macro I use when opening my Extra session. It's saved in a file with a .ebm extension. If you open that file, it should open the macro in the Extra macro editor. On the toolbar on the top of the window is a Help option. Click on that, click Find, and enter the word you want, for example "settletime". You should be able to find anything you need there. g_hostsettletime is the number of milliseconds that Extra will wait after issuing a command to the mainframe before continuing with its processing.

You might also get to the editor from an Extra session. Click on Tools > Macro > select one of the macros and click Edit.

You may have a different version of Extra, so your mileage may vary, but you should still be able to find the help screens from the macro editor.
