All FWEB commands begin with the character @
. It is recommended
that these begin in column 1 if possible. This is required in some
cases [e.g., the @x
, @y
, and @z
in change files
(see Change files), or column-oriented FORTRAN-77 processing].
Some of these control codes may be used anywhere; others begin a new
part of the current section. (For a discussion of sections and parts,
see Structure.) For a quick summary of the control-code mappings
and to see which codes begin new parts, say ftangle -@
.
See -AT.
