Another Program

Here is another program, similar to the previous program, but it does some computation with the values it reads.

INPUT "Enter file name:", NAME$   ' Ask user for a file name
OPEN NAME$ FOR INPUT AS #1
'
INPUT #1, NUM
LET SUM = NUM
'
INPUT #1, NUM
LET SUM = SUM + NUM
'
INPUT #1, NUM
LET SUM = SUM + NUM
'
PRINT "The Sum is:", SUM
END

The program first asks the user for the file name, then opens that file for INPUT. The file should be located in the same directory as the default directory of the program. The program reads the number on the first line into NUM. SUM is then initialized to that value.

Next, the program then reads in the next number in the file into NUM and adds NUM to SUM. Then it reads in the third number and adds that to SUM.

Finally it prints out the sum of the three numbers.
