Mnemonics

Mnemonic Categories

Mnemonics can be classified according to their use and the type of device they control. While there are exceptions where mnemonics can be redefined for use outside of their intended purpose, the following categories identify the standard mnemonics by their functionality as well as their names.

Category	Description
Behaviour	Mnemonics that are used to modify the behaviour of PxPlus specific to the channel on which they are defined.
Character Display	Mnemonics that are used only when sent to text-based CUI devices.
Character Printer	Mnemonics that are used only when sent to direct-to-output devices.
Definition	Mnemonics that contain a definition or provide information to be used by a device for performing specific operations.
Editing	Mnemonics that are used to control various editing operations in *both* text-based and GUI display environments.
GUI Display	Mnemonics that are used only in a graphical environment for output to the screen. See Note below.
GUI Printer	Mnemonics that are used only when sent to a graphical printer spooling system (i.e. WINPRT). See Note below.
Motion	Mnemonics that are used to direct cursor movement in *both* text-based and GUI display environments.
Note: In Windows, the 'FILL', 'FONT', 'PEN' and 'PICTURE' mnemonics use Graphical Device Interface (GDI) resources/handles that are only released when the window they are in is dropped or cleared, or their 'IMAGE' group is deleted.

The table below displays a list of mnemonics and indicates (with an X) the categories to which they belong.

Note:
All colour mnemonics (i.e. 'BLACK', 'BLUE', 'CYAN', 'GREEN', 'MAGENTA', 'RED', 'WHITE' and 'YELLOW') are supported on character printers, assuming that the required escape sequence was defined when setting up the printer. While most character printers only print with black ink, it is possible to print to an HP ink jet printer as a character device.
