in reply to Re: using symbol table lookup
in thread using symbol table lookup

My purpose is that my perl scripts read many text files
So rather than checking each one in each script, I thought
I would always make my filename variables always as
"something_file". And have a standard subroutine that checks
all %main:: scalar variables  =~ /\_file/ and do the checks
on each entry (Like file exists, file is readable etc.)
