procedure numeric max

Hi all,

I'm having some trouble trying to make it so the answer Max(3,1,x,4) turns into Max(x,4), that is, only the greates number and the non numerical values are returned. I've tried a bunch of different things, but have gone out of ideas.

This is the link to the Maple file :6-1.mw and this is the code:

``

> 

#Improve the general Max procedure on page 224 so that Max(3,x,1,4)returns Max(x,4). That is, the procedure returns the maximum numerical value along with all nonnumerical values.
> 

Max:=proc() local m, i;
m:=-infinity;
for i in (args) do
  if not type(i, numeric) then
    return 'procname'(args):
  end if;
  if i>m then
    m:=i
  end if;
end do;
m;
end proc;

proc () local m, i; m := -infinity; for i in args do if not type(i, numeric) then return ('procname')(args) end if; if m < i then m := i end if end do; m end proc

Max(3,1,x,4);

Max(3, 1, x, 4)
