Forums Scripts & Popups echo asc()

I tried searching for this cause I member seeing someone say it the other day, but what is the //echo $asc() command to get the ascii valuse of a character? I'm trying to use:

//echo $asc(,)

to get the value of , but it's saing too many parameters.

Use

to bring up a dialog in which you can enter the comma and get the value.

Thanks. I'm going to save it this time!
