@z...@x
- If a source or include file begins with ‘@z’ (in the very first
two characters of the file), then all material is skipped until and
including a line beginning in column 1 with ‘@x’ [except that
lines of the form ‘$Keyword: text of keyword $’ are processed; see
$KEYWORD, ATK_ (source files), or ATk (include
files)].
@%
- All material until and including the next newline is completely ignored.
@%%
- As ‘@%’, but also skip blank lines that immediately follow the current line.
For example,
@z
