DDE Commands Must Be Bracketed for Non-Windows Platform

SUMMARY

Dynamic data exchange (DDE) commands are not ignored in FoxPro for MS-DOS or FoxPro for Macintosh.

If you execute a DDE command, FoxPro for MS-DOS will produce the error message "Function not implemented." FoxPro for Macintosh will display the error message "Feature not available."

Use the system memory variable _WINDOWS to prevent the error messages from appearing. For example:

   IF _WINDOWS
      <DDE commands>
   ENDIF
				

The value of this system memory variable is determined by the version of FoxPro that is executing the code. You cannot use the STORE or = commands to change the value of this variable.
