Returns the ascii number of the character C.
echo -a $asc(A) ; returns 65.
To get the ascii value of a character, just type:
//echo -a $asc($?)
Type the character you want the ascii value of in the prompt and press enter. This is necessary as you can't use something like 'echo -a $asc(,)', as mIRC would think the comma is seperating parameters and so return '* Too many parameters: $asc'.
$chr returns the character of an ascii number.
