@deffn {Directive} %debug
In the parser implementation file, define the macro @code{YYDEBUG} (or
-@code{@var{prefix}DEBUG} with @samp{%define api.prefix @var{prefix}}), see
+@code{@var{prefix}DEBUG} with @samp{%define api.prefix @var{prefix}}, see
@ref{Multiple Parsers, ,Multiple Parsers in the Same Program}) to 1 if it is
not already defined, so that the debugging facilities are compiled.
@xref{Tracing, ,Tracing Your Parser}.
If the @code{%define} variable @code{api.prefix} is used (@pxref{Multiple
Parsers, ,Multiple Parsers in the Same Program}), for instance @samp{%define
api.prefix x}, then if @code{CDEBUG} is defined, its value controls the
-tracing feature (enabled iff nonzero); otherwise tracing is enabled iff
-@code{YYDEBUG} is nonzero.
+tracing feature (enabled if and only if nonzero); otherwise tracing is
+enabled if and only if @code{YYDEBUG} is nonzero.
@item the option @option{-t} (POSIX Yacc compliant)
