     Instructions:   Review the following program and see if you can 
                     predict the outcome by completing a "pencil 
                     trace" of the code.  

                     Program output is provided at the end of this 
                     page.

     Compiler:       The program was prepared using GWBasic, which  
                     requires the use of line numbers.


10 REM This program demonstrates the INPUT statement with
20 REM numbers and characters.
30 PRINT "Input a word at the ? prompt."
40 INPUT X$   ' Assume that you enter Basic at the ? prompt.
50 PRINT "Input a number at the ? prompt."
60 INPUT Y    ' Assume that you enter 9 at the ? prompt.
70 PRINT "The word is "; X$
80 PRINT "The number is "; Y
99 END
10000 REM And the answer is ...
10010 REM The word is Basic
10020 REM The number is  9
