I will try this way; read and then ad to new file.

Have You any big 'christmas card' -> 'money'- converter ready somewhere?

December is the right time to do this substitution example, because
every place are full of these christmas cards.

Don't worry about "evil functions", Richard, code seems to work very

No warnings, no errors in my test compiler as usual ;-)

I read these eskimo sites ("eskimo" name is an icecream stick here in
