Hi Elisha,
Thanks for your response. I'm able to get the names
of all the local variables inside the method as an
array. But I need to access the name of the variable
used in a particular instruction.
Ive another question actually. How will I determine
the value of a local variable within a method during
run time? I wanted to know whether a variable is null
or not. How will I determine this? Any help is
appreciated. Thanks for your time.
Thanks,
Eshwari
