Why % put in front of any shell derective?

[jinchun . peng]

Sir:
Why is a % put in front of any shell derective like the following? In terms
of your on-line guideline for makefile, % should not occur this way.
Any advice on this?


%ifdef VERBOSEFLAG
        .DEBUG_PRINT
        .DEBUG_RUN
% echo Windows: $(OS) Version: $(OSVERSION) Release: $(OSRELEASE)
% echo Windows: $(OS) Version: $(OSVERSION) Release: $(OSRELEASE) > CON
% exec $(MAKE) -V
% exec $(MAKE) -V >CON
% echo Running in VERBOSE mode for $(MAKEFILE) >CON
% echo Please wait ... >CON
% echo >CON
%endif
