You need a reverse scan.  There's no opcode or builtin for this, so
you'll have to code a loop.

    Something like this:

    len = 37
    for  i = 37 down to 1
    |   if  text(currentLine + i) is ' '
    |   |    len = i - 1
    |   |    exit the loop

If len is still 37, there's no blank and you have to break the string.
