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:
Copy VB0 string.Copy the string starting from the second character.The length of the
copy string is 3.The result is placed VB100.
