Re: char to numeric

[Vernon Hamberg <vhamberg@xxxxxxxxxxx>]

A superb (IMNSHO) writer on VB and Java, Gary Cornell, has 3 rules of 
optimization:

1. Don't!
2. Don't!
3. Don't!

He refers specifically to "cute" programming techniques that become 
unmaintainable.

The metrics reported here show little difference - we are not talking 
multiple orders of magnitude.

Just my $.02
