Returns I amount of charaters from the Nth charater in text.
$mid(<text>,N[,I])
I is optional, if I is ommited, 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 charaters (3) so we grab b=1 c=2 d=3
This is an example to loop threw every character and check it against something.
;Set the variable %text to the string we are going to use. var %text = There are 14 brown cows, they're hyperactive and jump over the 6 lazy red fish. :-( ;Set the variable %n to 1 and %i to the length of %text. var %n = 1, %i = $len(%text) ;Creates these local variables so they don't save as global when used. var %letters = 0, %numbers = 0, %spaces = 0, %other = 0 ;Keep looping while %n is less than or equal to %i. while (%n <= %i) { ;Set %letter to the charater located at %n, only grab 1 charater. var %letter = $mid(%text,%n,1) ;If %letter is a letter, number, space or other set the corresponding variable. if (%letter isletter) { inc %letters } elseif (%letter isnum) { inc %numbers } elseif (%letter == $chr(32)) { inc %spaces } else { inc %other } ;Increment %n by 1, so first loop %n = 1, then %n = 2 until %n is greater than %i inc %n } echo -ag String: %text echo -ag There are %letters letters, %numbers numbers, %spaces spaces and %other other charaters (punctuations etc.)
