3. Calculation of the memory required for bookings
Booking: Each booking occupies 9 bytes. Multiply this value by the number of bookings to be stored
and enter the result in the column total.
A unique fixed value of 45 bytes is required for the bookings. Add this value to the value of
the field total and enter the result in the field memory requirements.
Enter the value of the field memory requirements in the field subtotal 3.
Add the values of the fields Subtotal 1, Subtotal 2 and Subtotal 3 and enter the result in the
field ‘
Required total memory ’.
4. Analysis of the required RAM extension
Enter the value of the field total memory requirements, rounded up to the next whole number, in the 4 blank
highlighted fields and subtract this value from the free memory space shown above. If the result of any of
these subtractions is 0 or any positive value, a memory extension is required for that column.
