Answer:

Memory is reserved for the variable NUMBER, since NUMBER has not been used before in the program.

Details of the LET

Recall the details. A LET Statement:

  1. Finds memory for each NEW variable in the statement.
    • If there are no new variables, this step does nothing.
  2. Does the calculation on the RIGHT of the equal sign.
    • If there is nothing to calculate, it just uses the value that is there.
  3. Replaces the contents of the variable to the LEFT of the equal sign with the result of the calculation.

QUESTION 4:

Assume that memory has just been reserved for NUMBER in the LET statement. What happens NEXT as the LET statement executes?

' Example LET statement
LET NUMBER = 5 + 2
PRINT NUMBER
END
