Thank you, jaredor.

Moose looks interesting - but is, I am afraid, beyond me at this stage. However, the link to Conway is most helpful.

However, I was actually looking for advice on the parsing of the file. Unless there is a better way, I am likely to do a regexp on the first word of each line, and use a switch statement to subsequently process and store the data.

Thanks again.
