Following a couple of posts mentioning 03xx numbers, I just checked my 
code which mangles ofcom's numbering data for my hotel telephone billing 
applications, and discovered that ofcom do not list 03xxx numbers in 
either sabc.txt, nor s1_code.txt

Most annoying.  (That and the current issue of s1_code.txt has a badly 
formatted line at the end of it that I'll have to code around). (As 
s1_code and s3_code have the same format, a bit of
	LC=`wc -l s3_code.txt`; tail -`expr $LC - 1` >>s1_code.txt
prior to the data mangling program should do the trick...

If you are munching on the sabc.txt and s1_code.txt data to produce 
itemised telephone bills with call descriptions and so forth on them, 
you better examine your code too, or the 03xx numbers will come back to 
bite you...
