charAt Method

Returns the character at the specified index of a String object.

function charAt(index : Number) : String

Arguments

• index
  Required. Zero-based index of the desired character. Valid values are between 0 and the length of the string minus 1.

function charAtTest(n)
{
   var str = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
   var s = str.charAt(n - 1);
   return(s);
}
