in thread DB search results using DBI...execute

Dont forget to fix the if ($#arr eq 1) { test too. its either if ($#arr eq 0) { or if (sclalar(@arr) eq 1) {

    wow. so many different ways to do things, makes it hard to keep track of which is right lol. ok. so, i changed it from $#arr to scalar(@arr) i'll have to rip through some 30,000 lines of code to fix that issue. do i have to use if (scalar(@arr) eq 1) or would if (@arr eq 1) work the same?

      if (@arr eq 1) does work the same, i just think  if (scalar(@arr) eq 1) is clearer, and i dont play golf

      if (scalar(@arr) == 1) might be cleaner/faster too, eq "causes" each side to get cast into char
