• (send a-text find-string-all str direction start end get-start? case-sensitive) -> list of exact non-negative integers
     str : string
     direction = 'forward : symbol in '(forward backward)
   start = 'start : exact non-negative integer or 'start
   end = 'eof : exact non-negative integer or 'eof
   get-start? = #t : boolean
