RE: sub routine

Hi Christ 
   
         In sub Dist() , you need define scope of each variable as my or our or 
local , which is line no.20 . 

Regards
Sunita

Thanks Uri.

I've been reading perldoc perlsub and have a better understanding about 
subroutines, but I am still stuck. Any help is greatly appreciated.

The error I am getting is:

Global symbol "%record" requires explicit package name at ./DOband1.pl line 20.
