Node:Comments, Next:Boolean Flags, Previous:Case insensitivity, Up:Words
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.
\G
compilation 'ccc<newline>' -- ; run-time -- gforth ``backslash-gee''
Equivalent to \
but used as a tag to annotate definition
comments into documentation.
