The information in this article applies to:

  • Microsoft FoxPro for Windows, version 2.6
  • Microsoft FoxPro for MS-DOS, version 2.6

SYMPTOMS

#IFDEF works differently in dBASE and FoxPro. FoxPro cannot use #IFDEF and #IFNDEF. Instead, FoxPro uses #IF, which takes only a logical value or a number (0 = false, 1 = true).

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in FoxPro 2.6a for Windows and MS-DOS.

RESOLUTION

To work around this problem, issue an #IF statement instead. For example: 

   #IF D=1
      ? "TEST"
   #ENDIF

MORE INFORMATION

The following code demonstrates how #IFDEF works in dBASE and FoxPro: 

   *** #IFDEF Example ***
   #IFDEF d
       ? "TEST"
   #ENDIF
This code works properly in dBASE and does not print "TEST". However, in FoxPro, "TEST" is printed. This means that any dBASE code that uses #IFDEF will produce unexpected results when executed in FoxPro.
