     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 conditional branching
20 REM (IF THEN ELSE).
30 X = 100
40 Y = 200
50 IF X < Y THEN Z = X ELSE Z = Y
60 PRINT X, Y, Z
99 END
10000 REM And the answer is ...
10010 REM  100           200           100
