Answer:

No — you can write powerful programs without using arrays. But sometimes the complicated way is much easier (a backhoe is more complicated than a shovel, but easier to dig ditches with).

Calculated Subscript

Here is an example of things getting a little bit complicated:

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 = 1
LET HOTDATE$ = DAY$(WHICH+2)   
PRINT "Important date on:", HOTDATE$ 
END

In this program, the subscript in the last LET statement is the result of a calculation.
