Detecting Existing Variavble

[invoso.com]

In our script we need to detect RV exists no matter which value.

 

For example to recognize dialer scenario we need to detect existing $RV[OutDial_GUID] in terminating script to make additional steps.

 

How to do this?

Evaluate Expression module is one way. Evaluate this expression:

 

"$RV[OutDial_GUID]"

 

True/Success path will be taken if value is non-empty

False/Fail path will be taken if value is empty

 

 

You can use it in a VBScript module as well:

 

If "$RV[OutDial_GUID]" = "" Then

...

Else

...

End If

 

etc..
