ASE=Athens stock exchange
i ve posted some years before a similar message to this list and it
was suggested to make a patch  for this purpose.
Since i m not a programmer i would like to ask how easy is  to take
another module  xxx.pm and modify it?
Is there any particular requirements for the source format  of prices
? (i found a text , html, and xsl soures)
