I search large text files line by line for keywords. If I get a hit, I read the entire file into a scalar variable.

These files contain several instances of delimited sections. I then loop through the scalar variable, searching each instance of the delimited section for a keyword.

I use the global search if($string =~ m/regex/gix) to test if a regex matches a string (scalar variable). If I get a hit, I process that section.

My problem is, the text files are getting even larger. Not consistently, but often enough that I must have a procedure for handling them. If the file is too bloody large, I can no longer simply read it into a scalar variable.

I have to replace my wonderful global search with..., well, I don't know what, yet. Any ideas?
