This variable sets the maximum number of files that can be opened by the run-time system. The default value is 32. Keeping this value small conserves memory. Many operating systems limit the number of files that can be opened by a single process, so you may have to make some adjustments there too. The maximum value of MAX_FILES is 32767. The new higher limit of MAX_FILES is only available for objects compiled to version 6.2 or later. If MAX_FILES > 255 is used, all objects in use must be compiled to object version 6.2 or later. Failing to do this may lead to undefined behavior.
