You can output certain characters as symbols using the addition ... AS SYMBOL. You should only
address these characters with their system-defined names. The include <SYMBOL> (or the more comprehensive include <LIST>) contains the relevant identifiers as constants, e.g. SYM_PHONE, SYM_CIRCLE.
(List of symbols, Proposals for use).
Example
INCLUDE . WRITE: / SYM_RIGHT_HAND AS SYMBOL, " output as symbol 'Tip, Note',
SYM_LEFT_HAND AS SYMBOL. " output as symbol
Note
An output length of one character is enough for most symbols, but some (e.g. SYM_FAX) are twice as long.
You can determine the length of a symbol with DESCRIBE FIELD SYM_... OUTPUT-LENGTH ...
