Aha!  So, the fact that I am used to Delphi code (i.e. am using Exceptions 
and such) and am reading about internet programming in freepascal for the 
first time has knobbled me!

Thanks very much, reverting the Integers to Words has solved my problem, 
and I will look out for any changes in future, I'm stumped as to why it 
compiled and ran previously, but now I don't care. :)

You have made me a happy man. Thank you.
