Returns I amount of characters from the Nth character in text.
$mid(<text>,N[,I])
I is optional, if I is omitted, it will return from position N onwards.
Examples
var %i = abcde echo -ag $mid(%i,2,3)
This above example will echo out bcd. This is because it grabs the text from position N which is 2 in this case, a being 1, and b being 2. From this spot, we now grab then next I characters (3) so we grab b=1 c=2 d=3
This is an example to loop threw every character and check it against something.
