$L_KEYWORD
: Value of local RCS-like keywordFor most purposes, ‘$L_KEYWORD’ behaves as ‘@k’ (see ‘@k’: Access local RCS-like keyword). It is still under development and should not be used yet.
‘$L_KEYWORD("Keyword")’ extracts (as a character string) the text of an RCS-like keyword defined in the ignorable commentary between ‘@z’ and ‘@x’ at the beginning of a file included via ‘@i’. ‘$L_KEYWORD("local keyword")’ is expanded during input, and the results are known only during the time the include file is being read.
Note that the argument of ‘$L_KEYWORD’ must be a quoted string.
For more discussion of the distinction between local and global
keywords, please see ‘@z’: Begin ignorable material, or terminate change and $KEYWORD
: Value of global RCS-like keyword.
It is expected that local keywords will rarely be used, as fundamental revision-control information should presumably be extracted from the top of the master web file.
