Identifier
The identifier for the $WARN directive: UNIT_PLATFORM
Description
The whole unit is tagged (using the platform hint directive) as one that contains material that might not be available on all platforms. If you are writing multi-device applications, the unit might cause a problem. For example, a unit that uses objects defined in OleAuto might be tagged using the PLATFORM directive
The $WARN UNIT_PLATFORM ON/OFF compiler directive turns on or off all warnings about the platform directive in units where the platform directive is specified.
