Thanks. I did try that but for some reason thought it hadn't worked!
On a vaguely related note, if I have a fraction, e.g. 999r1000, how can I 
isolate the numerator and denominator?
I was thinking of formatting as a string, and then I can do this:

   'r' i. ":999r1000
1 1 1 0 1 1 1 1

I was hoping to be able to go from there to by knowing where the 'r' is, but I 
can't think of how to do it. I'm still finding it hard to stop thinking like 
it's C.
