Obs erve that this program ends only if the tr ansac tion amount is zero. The second IF state ·
m en t is the one wh ich illustrates the structure we mentioned befor e. Not ice that in addi ti on
10 the two separate act io ns associated with the IF statement (lines 50 and 70), there are some
statements (lines 80 and 90) executed regardless of the r es ult of the IF testing.
We can no .. v wr it e a third version of the program from the previous section:
Pr ogram Listing:
10 PAUSE "ARE YOU AS LE EP?"
20 INPUT " TYPE Y ES OR NO "; SXS
30 IF
SXS < > "YES" THEN GOTO 99
40 PRINT " OH, SORRY TO DIS TURB YOU"
99 END
