Have a look at package for more info. `main::` is the default. If there are no other packages that's the one your in and there is no need to include the prefix. If there is a package (e.g. a module) that has a variable of the same name then you would need the package prefix to distinguish between the two.	[reply] [d/l]

Ok. That means both $main'ora_errstr & $ora_errstr belongs to the same package. Then $main'ora_errstr = $ora_errstr doesn't make any sense. Actually $main'ora_errstr = $ora_errstr this statement is defined in the subroutine of ora package. This package is being called by many other scripts. Some of the scripts use $ora'ora_errstr & some $main'ora_errstr. I am really confused. Please help me.	[reply]
