Replaces a byte in some string variable, Str1 to Str0, using a decimal number 0 thru 255 in replace_with_this_byte within that string at this specified offset (at_this_byte), all of which start at zero. You will get an error if you try to overwrite something past the end of this string.
Since the specified string is edited directly, there will be no output and thus keep Ans intact, except if an error occurred. This means you cannot put in an immediate string as nothing but a discarded temporary variable will have been changed. Useful for quiety editing a string.
