Our initial example could be reconstructed as: NEXT Write a short program that takes as input a pair of numbers -- month and day. If you're interested in studying more of what Basic can do, and what a compiler can add, the Advanced Tutorial will help. Eg, try the following to see how each is interpreted:

Note that I've used an alternate way of designating the length in line Another problem is the fact that most people have trouble conceptualizing more than 3 or 4 dimensions. These allow us to process parts of strings. This uses an extra byte per line, but makes data files easier to display and programs easier to debug.
OPEN is used by both types of files, but has a different syntax for each. Watch what happens when borders overlap.
Try taking these out and see why. Some computers such as the IBM PC define an additional set for the numbers baasic these are not standardized. One of the strengths of the LINE command is also a drawback.
