Eng:Inserting a Character into a String

Working with strings can be difficult with limited options, but there are almost always workarounds. In a string, a character can be added. This tutorial explains the concept of inserting a character in a string. The scripts below are custom blocks that are easier to work with. There are two basic methods for performing this: the Variable Method and List Method.

Variables Method
In this method, assume the following:
 * (changer) is the variable used to work with the transition of the character to the desired one
 * (item#) is the variable used to iterate through the string
 * (string) is the string input in the custom block that represents the character being inserted

define add (new character) at (character#) of string //"string" is text to notify you what variable you change set [changer v] to [] //this is blank set [item# v] to (1) //so the string transfer begins with the first character repeat ((character#) - (1)) //repeats the amount of characters before the one going to be inserted set [changer v] to (join (changer) (letter (item#) of (string))) //adds the current character to "changer" change [item# v] by (1) //moves on to the next character end set [changer v] to (join (changer) (new character)) //adds the new character repeat ((length of (string)) - (character#) //repeats the amount of characters after the inserted one set [changer v] to (join (changer) (letter (item#) of (string))) //adds the current character to "changer" change [item# v] by (1) //moves on to the next character end set [string v] to (changer) //stores the new string in the specified variable

add [] at of string //this is what the custom block looks like

List Method
For this method, assume the following:
 * (item#) is the variable used to iterate through the string
 * (letters) is the list which separates each letter of the string and modify it
 * (string) is the result of adding the new character to the string

define add (new character) at (letter #) of (string) //"string" is a string input that represents the character being inserted set [item# v] to (1) //the transferring of the variable's letters to the list starts with the first character delete [all v] of [letters v] //clears the list of letters repeat (length of (string)) //repeats the amount of characters there are in the variable represented by the input (string) add (letter (item#) of (string)) to [letters v] //adds the current letter as a new item to the list change [item# v] by (1) //moves on to the next letter end insert (new character) at (letter #) of [letters v] //inserts the new character set [string v] to (letters) //the variable is then set to the list of letters. (letters) is a combination of each letter of the list in own string

add [] at of [] //this is what the custom block looks like
