  I think you want your third line to read:
if ( ${page[1]} == "q" ) exit

  (Note that just out of habit I use {} around variable-names, and double
quotes around strings... you probably don't need them, but I'm not sure.)
  I think your problem was the if was getting expanded to:
    if ( 5 plot == 'q' ) exit
