Observe that this program ends only if the transaction amount is zero. The second IF $late·
ment is the one which il lustrates the structure we mentioned before. Notice that in addition
to the
t\\IO
separate actions assoc iated .. ..,ith the IF statement (lines 50 and 70). there are some
statements (I ines 80 and 90) executed regardless of the result of the IF testin9.
We can now write a third version of the program lrom the previous section:
Program Listing :
10 PAUSE "AR E YOU ASLEEP?"
20 INPUT "TYPE YES OR NO "; SXS
30 IF SXS <>" YES" THEN GOTO 99
40 PRINT "OH. SORRY TO DISTURB YOU"
9'9 END
