Hi Dave
Just Wire the Tab Control to an Integer Numeric Indicator. The Tab Control is of Enumerated type. So If from first Page It will be 0, 1 ,... etc. Based on what Page is Showing.
If your Tab Is an Indicator, Use the Value Property or Local Variable to read the Value.
I am Using 6.1 Jumped from 5.1 to 6.1.

Good Luck!
