Rajani,
I misunderstood it in the first place.
I think debugger would be easier. Set a breakpoint with "Break when expression is true" and put your expression as a match to another public variable (TrackingVar). ie:

!(Type('m.MyVar') = Type('m.TrackVar') and m.MyVar = m.TrackVar)

Clear All
Release All extended
On key label f2 m.TrackVar = m.myVar
Public TrackVar,myVar
? "Starting ..."
Function1("Hello")
Function2()
Function3()

Function function1
Lparameters tcStr
MyVar = Upper(m.tcStr)

Function function2
For ix=1 to 10
 ? ix
endfor
MyVar = "there"

Function function3
MyVar = "again"

PS:Still against public vars:)
