_macPlus | 3 | System(_macPlus) always returns 0. |
_aplRes | 4 | Reference number for the Application file's resource fork . |
_maxColors | 10 | Maximum color bit-depth available on the main monitor. Use the expression (2 ^ System(_maxColors)) to get the actual number of available colors. |
_cpuSpeed (PPC only) | 15 | System(_cpuSpeed) returns the current clock speed (in megahertz) of the microprocessor. |
_clockSpeed (PPC only) | 16 | System(_clockSpeed) returns the Gestalt clock speed (in megahertz) of the microprocessor. |
_aplvRefNum (Appearance Manager) | 18 | This is the volume reference number of the running application. vRefNum usage is obsolete |
_aplparID (Appearance Manager) | 19 | This is the volume parent ID number of the running application. parentID usage is obsolete |
