Several INPUT Statements

Often a program needs several values from the user. There are several ways this can be done. A good way is to prompt and input the values one by one.

The following program calculates the cost of a phone call. The user enters the number of minutes of the call and the cost per minute.

' Cost of a phone call
'
PRINT "Enter number of minutes" 
INPUT MINUTES

PRINT "Enter cents per minute"
INPUT RATE

PRINT "Cost of the call in dollars:", MINUTES*RATE/100
END

Blank lines have been put in the program to make its operation more clear. The blank lines are just skipped (like comments) when the program runs.

When this program is run, the first PRINT statement will prompt the user. Then the first INPUT statement will get a number from the user and put it in MINUTES:

Enter number of minutes
? 23

Now the next PRINT statement will prompt the user and the next INPUT statement will get the value and put it in RATE:

Enter number of minutes
? 23
Enter cents per minute
? 10

Finally the last PRINT statement will perform the calculation using the numbers in the two variables, and print the result to the screen:

Enter number of minutes
? 23
Enter cents per minute
? 10
Cost of the call in dollars:  2.30
