Graham,
Would it help to use another web site? Not as long as the program works on this
site. If it doesn't it may help to change sites, but
a new reader would have to be crafted. Towards this my code may look
intimidating. It isn't really a good example for a demo,
because it looks scary. As I said, I experimentally stretched the envelope.
The trick is to develop incrementally, one step at a time, look at the
result of each stage, recognize what needs to be done
next and add missing definitions or add a subsequent translation step. In this
manner a complex system can be built. SE is
particualry accommodating in this respect. You can test an Editor object in
seconds on the IDLE command line, e.g.:
>>> s = 'Total: $1,234.55 (-6.7)'
>>> print SE.SE ('"$=USD " ,=\' .=, ":= " )=%)') (s)
Total USD 1'234,55 (-6,7%)
It also helps to read SE-DOC.HTM which explains a host of basic techniques.
Glad to help
Frederic
