Flags
Precautions The maximum number of characters is 4,095 (0FFF hex). If there are more
than that (i.e., if there is no NUL before the 4,096th character), an error will be
generated and the Error Flag will turn ON.
If 0000 (hex) is output to D, the Equals Flag will turn ON.
Example In this example, LENS$(650) is used to calculate the number of characters
and output the result.
