Mnemonics |

Mnemonics are special control sequences for output to a display device or printer. Mnemonic instructions are inserted within a PRINT or INPUT statement and are specific to the channel on which they are defined. The language provides an extensive list of predefined mnemonics; however, additional two-character mnemonics may be created via the MNEMONIC directive.

Below is a list of some commonly used mnemonics. For a list of all mnemonics, see Mnemonics.

'BR' | Begin reverse video mode.
'CE' | Clear from cursor to end of screen.
'CH' | Position cursor at home; i.e. @(0,0).
'CL' | Clear from cursor to end of line.
'CS' | Clear screen.
'DEFAULT' or 'DF' | Set current attributes as defaults (color, foreground/background, etc.).
'FF' | Advance page (issue form feed).
'LF' | Advance one line and return to column 0 (line feed).
'RED' & '_RED' | Input/output will be in red foreground or background (see the list of Mnemonics for other colors).
'RM' | Reset to default attributes.
