In one of my perl scripts i have a global array @pf_info
In one of my functions - i build this array. Now say it has the @pf_info has 2 elements.

In the same code, in my next function i empty the array saying
@main::pf_info = ();
and try and build the array with some other variables. But when i print the array, i see that the pf_info has the older 2 elements + the new list.

Is the way i am initializing incorrect?

Pleas bear with me is u find my problem silly. But please give me some suggestion...

in theory your description seems like it would work.  but i haven't actually seen the code.  your description describes what you want to happen while the code may have a slightly different interpretation.

one of your functions may be out of scope.  if you use "my" or "local" or "use strict" anywhere, or frequently use package names like "main" and other times not.. you could have scope problems somewhere.  essentially this would cause a change to take place locally, but not globally.

this is just a hunch.  also, try using "undef @main::pf_info" instead of "@main::pf_info = ()" and see if this helps.
