IsAlpha() etc..

Hello Waynes,

Thanks a lot for your tips, they are very valuable ! I've seen you've used the Ascii number for testing if the char was a digit. But in PureBasic you can directly use the following stuff (much faster to develop as you don't need to know all the Ascii table by heart :

If Asc(char) >= 65

Can be changed to:

If Asc(char) >= 'A'

I hope this help !
