Godfrey/Jaime,

I've built a 'converter' for a client. That converter will read data from a tab-delimited file and write the same data to another tab-delimited file, but it will also modify and add certain fields. Examples of added fields are a recno-field and a field filled with a random number. Now, the customer wants yet another field added with generated values. This time he needs a field that will contain values that comply to the (standard) normal distribution rule. The number of records of the produced file is undefined, but in reality it are almost always millions of records (uptill even 250 million!). The resulting file is used in an OLAP-tool (data-mining).

Constructive frustration is the breeding ground of genius.
If there’s no willingness to moderate for the sake of good debate, then I have no willingness to debate at all.
Let's develop superb standards that will end the holy wars.
