     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 

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

10 REM This program demonstrates a simple FOR X = Y to Z loop.
20 X = 1
30 Y = 3
40 FOR Z = X TO Y
50   PRINT "Z = "; Z   'Notice how this line is indented.
99 END
10000 REM And the answer is ...
10010 REM Z =  1
10020 REM Z =  2
10030 REM Z =  3
