Answer:

Enter a number
? 17
The number is zero or positive
Positive numbers are > 0
Bye

The TRUE branch was executed because the answer to the question NUMBER >= 0 was TRUE. The true branch consists of two statements this time.

Outline of a Two-way Decision

Here is how an outline of how to make a two-way decision:

... statements done before the decision
'
IF condition THEN
    ....  ' true branch
    ....  
    ....  ' true branch
ELSE
    ....  ' false branch
    ....
    ....  ' false branch
END IF
'
... statements done after the branch comes back together

Here are some details:

The IF condition THEN must be on one line.
The condition compares variables and values.
- The statements in the true branch must be one per line.
- There can be as many statements in the true branch as you need.
The ELSE statement must be by itself on a line.
- The statements in the false branch must be one per line.
- There can be as many statements in the false branch as you need.
The END IF statement must be by itself on a line.

The condition looks like the part of a DO WHILE condition statement that compares what is held in a variable with other values. You can use the same comparisons: <, <=, =, and so on.

QUESTION 6:

Is the following program correct?

PRINT "Enter a Number"
INPUT NUMBER
'
IF NUMBER >= 0 THEN
  PRINT "The square root is:", SQR( NUMBER )
ELSE  PRINT "There is no square root"
  PRINT "Run the program again."
END IF
'
PRINT "Bye" 
END
