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.
