Forth supports two styles of comment; the traditional in-line comment,
( and its modern cousin, the comment to end of line;
(compilation 'ccc<close-paren>' – ; run-time – core,file “paren”
Comment, usually till the next
): parse and discard all
subsequent characters in the parse area until ")" is
encountered. During interactive input, an end-of-line also acts as
a comment terminator. For file input, it does not; if the
end-of-file is encountered whilst parsing for the ")" delimiter,
Gforth will generate a warning.
\compilation 'ccc<newline>' – ; run-time – core-ext,block-ext “backslash”
Comment till the end of the line if
BLK contains 0 (i.e.,
while not loading a block), parse and discard the remainder of the
parse area. Otherwise, parse and discard all subsequent characters
in the parse area corresponding to the current line.
\Gcompilation 'ccc<newline>' – ; run-time – gforth “backslash-gee”
\ but used as a tag to annotate definition
comments into documentation.
