Using INPUT with Subscripted Varibles

Here is a tiny program that uses an INPUT with a subscripted variable.

DIM RAIN(1 TO 3)                '  The array will store the rainfall
                                
PRINT "Enter rainfall for day 1:"
INPUT RAIN(1)

PRINT "You entered:", RAIN(1)
END

Here is a run of the program:

Enter rainfall for day 1:
? 4.37
You entered:  4.37
