ASCII constant string data type format ：
String is a series of characters, each character is stored as a byte.The first byte of a
string defines the length of the string, that is the number of characters.If a constant
string is entered directly into the program editor or data block, the string must start
and end with double quotation marks ("string constant").
Example:
When M0.0 is 1,string starting with VB0 is copied to the string starting with
VB100 .VB100 storage is an integer 6 ， VB101 storage is character "1" ， VB102 storage is character "2" ， VB103 storage is "3" ， VB104 storage is "4" ， VB105 storage is "5" ，
