Marshall,

 

Are you saying that a foreach loop would be just as fast as what Limbic-Region was suggesting for an array? Consider the following solution concept, which is what I had before, that I don't think is nearly so fast (though I didn't time it precisely).

foreach $replace (@substitutionlist) {

     ($oldline, $newline) = split(/\t/, $replace);
     $newline = s/\s/_SPACE_/g;
    #….more code here

     foreach $line (@array) {
          $count += s/\b$oldline\b/$spliced/eg for @array;
          #….more code here
     }
}
s/_SPACE_/ /g for @array;

Consider that @substitutionlist has over 10,000 lines, and @array has over 30,000, with many lines requiring multiple substitution replacements on a single line. Is the foreach setup outlined above really just as efficient?
