210 THE FOLLOWING PROGRAM ASSUMES THE READER IS FAMILIAR WITH THE
220 FIRST SECTION OF THE BASIC MANUAL, THE USE OF SUBSCRIPTED VARIABLES
230 AND THE USE OF THE DIM STATEMENT.

250 THE FIRST EXERCISE TO HELP YOU LEARN ABOUT MATRICES IS TO TYPE A

270 AND GET THE MACHINE TO PRINT IT OUT IN REVERSE ORDER.

300 TO READ THE DATA IN AND THEN PRINT THE NUMBERS OUT AGAIN.

330 20 FOR I=1 TO 5
340 30 READ A(I)
350 40 NEXT I
360 50 FOR I = 5 TO 1 STEP -1
