Re: Scanning for numerics in a comment field

This is from 1998, so there are no doubt better ways today, but it shows 
a way to eliminate all of the characters except the ones you list in a 
constant.

Essentially you can define a 40-element array of 1-character each.  Then 
 do a for/endfor loop, reading and saving digits. When I find a digit I 
start a new record.  If i am reading digits and find anything but a 
digit, then the record is done.  That way I can have several invoice 
numbers per 40-char. comment.
