     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) and Boolean logic (AND).
30 A = 100
40 B = 200
50 IF A > 10 AND B < 201 THEN PRINT "X"
99 END
10000 REM And the answer is ...
10010 REM X
