in my mp file, i defined two macros, say foo, bar,  using def ...
enddef;   then in the main figure, i call foo followed by bar.  And, i
used z1, z2 in both foo and bar as temporarily.  but the metapost
reported "Inconsistent equation" when it processed in calling of bar.
i think i need to make z1, z2 local in foo and bar respectively, but i
failed, because "save z1, z2" will cause another errors.  what's the

thanks in advance.
