The terminating quote may be left off. By default, strings are initially empty so the assignment is not necessary. Another way to check for an empty string is to use the LEN function.
<lang basic> 10 LET A$ = "
40 IF LEN (A$) = 0 THEN PRINT "THE STRING IS EMPTY"
50 IF LEN (A$) THEN PRINT "THE STRING IS NOT EMPTY"</lang>
