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.  
240  
250  THE FIRST EXERCISE TO HELP YOU LEARN ABOUT MATRICES IS TO TYPE A 
260 PROGRAM TO READ  IN A FIVE ELEMENT ROW VECTOR FROM A *DATA* STATEMENT
270 AND GET THE MACHINE TO PRINT IT OUT IN REVERSE ORDER.
280  
290   YOU SHOULD NOT USE *MAT* STATEMENTS; JUST USE TWO *FOR NEXT* PAIRS
300 TO READ THE DATA IN AND THEN PRINT THE NUMBERS OUT AGAIN.
310 THE PROGRAM SHOULD LOOK SOMETHING LIKE THIS:
320   10 DIM A(25)
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
370   60 PRINT A(I) ;
380   70 NEXT I
390   80 DATA 13,14,15,16,17
400   90 END
