The Subscript can be a Variable

Well, that was easy. To ask for the 6th item in the array, all you do is use subscript 6. What if the 6 is kept in a variable? Inspect the following program:

DIM DAY$(1 TO 7)    	          ' Make an array of seven strings
LET DAY$(1) = "Monday"            ' Make "Monday" the first item
LET DAY$(2) = "Tuesday"    
LET DAY$(3) = "Wednesday" 
LET DAY$(4) = "Thursday"     
LET DAY$(5) = "Friday"    
LET DAY$(6) = "Saturday"     
LET DAY$(7) = "Sunday"    

LET WHICH = 6
LET HOTDATE$ = DAY$(WHICH)    
PRINT "Important date on:", HOTDATE$ 
END

The program uses correct syntax. The expression DAY$(WHICH) is a correct subscripted variable.
