Re: checking for numeric chars

[Rick_Creel@AONCONS.COM]

You can use the INSTR command.

Assuming that $char is a single character that you want to test to see if its
numeric, you could:

let #position = instr('0123456789',$char,0)

If #position > 0, then $char is numeric
If #position = 0, then $char is not numeric

OK, this is a beginners question, and I know various answers, so I'll ask
it as a best practices question...

What's the *best* way to check if a character is numeric (0-9)in SQR?
