-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft FoxPro for Windows, versions 2.5, 2.5a, 3.0, 3.0b, 5.0, 6.0 
 - Microsoft FoxPro for MS-DOS, versions 1.02, 2.0, 2.5, 2.5a 
-------------------------------------------------------------------------------

SYMPTOMS
========

Attempting to print a single brace ("{" or "}") with the ??? command results in
a syntax error because FoxPro expects a matching pair of braces in the command
line.

CAUSE
=====

The ??? command sends text directly to the printer. This method is normally used
to send "Escape" codes to change printer settings. Using braces is one of three
ways to identify ASCII characters. For example, each of the following identify
the letter "k" (107 on the ASCII chart):

 - CHR(107)

 - "k"

 - {107}

FoxPro expects braces in pairs when the text is evaluated with the ??? command.
If text (either a string or file) is sent to the printer using the ??? command,
and the text includes a single brace ("{" or "}") without a matching brace on
the same line, FoxPro detects the first brace as the beginning or end of an
ASCII character code sequence.

RESOLUTION
==========

Replace all single left braces ("{") with "{123}" and single right braces ("}")
with "{125}". "{123}" will be interpreted as ASCII 123 and the "{" will be
printed out and likewise for the right brace.

The following snippet provides an example:

      SET PRINTER TO xxx.txt
      ??? "{123}"
      SET PRINTER TO
      MODIFY FILE xxx.txt

The text file will contain a single left brace.

Another alternative is to use "{{}" and "{}}" to output a single left and right
brace, respectively. The following command, if used in the above code example,
will also output a single left brace to the text file:

      ??? "{{}"

STATUS
======

This behavior is by design.
