why put $asc(\\,) when you could just put 44 in place of the lot.
To find out what the $chr is for it. Obviously, if you know the $chr number, you don't need to worry about it. And, yes, I know comma is 44. However, there are times when I have to figure out some of the others that I rarely use $chr for and $asc won't give me an answer.
I suppose I could just create a list somewhere and when I come across the need for them, I'd just look on the list, but I like being able to just use //echo -a $asc(N) to get the value for N. And I thought I had seen something on this forum about how to do that. Just don't remember it anymore and wouldn't have any idea what to search for to find it again.
