MORE INFORMATION
================

Steps to Reproduce Problem
--------------------------

1. Run the following code:

        SET PRINT ON
        SET PRINT TO
        SET PRINT TO test.txt
        ?CHR(27)+"YES"+CHR(0)
        ?
        SET PRINT TO
        SET PRINT OFF

2. After the program has executed, you must quit FoxBASE+. At the MS-DOS prompt,
  issue the following command:

  " DEBUG test.txt d " (without the quotation marks)

  The following line of hexadecimal characters will be displayed:

  0D 0A 1B 79 65 73 0D 01-8B C3 48 12 B1 04 50 50 1B hex=chr(27) 79 hex=Y 65
  hex=E 73 hex=S

  NOTE: "00 hex" is not present after "73 hex".

3. Press Q to quit Debug.

If the same code is executed in FoxPro versions 1.02 and later for MS-DOS, Debug
will produce the following line of hexadecimal characters:

  0D 0A 1B 79 65 73 00 0D-0A C3 48 12 B1 04 62 75

  1B hex=chr(27)
  79 hex=Y
  65 hex=E
  73 hex=S
  00 hex=chr(0)
