delStr

>>-delStr(n--+---------+--)------------------------------------><
             +-,length-+

Returns a copy of the receiving string after deleting the substring that begins at the [n] th character and is of [length] characters. If you omit [length] , or if [length] is greater than the number of characters from [n] to the end of [string] , the method deletes the rest of [string] (including the [n] th character). The [length] must be a positive whole number or zero. The [n] must be a positive whole number. If [n] is greater than the length of the receiving string, the method returns the receiving string unchanged.
