But for this specific case it is very compact and elegant (IMHO).

So, I should not split the string into lines?

An useful feature of my program is that it parses both an input like:

1:
1046323,2005-12-19

and
1:
1046323


If I write a parser from scratch I need to implement two separate functions.

I will give it a try, just to check if it has better performances.


Thanks  Manlio
