I have a question... Suppose I want to write a macro like

#macro Stuff(X, Y)
  X+Y
#end

Now, that's fine if I do

sphere {<7, 2, -6>, Stuff(11, 4)}

but if I try

#declare Banana = Stuff(6, 14);

I get a "no semicolon" error message. Is this a bug? Is there a way
round it? (Obviously the same thing occurs with vectors and colours.)

Thanks!
Andrew.

Are you sure your macro doesn't look something like

#macro Stuff(a)
#if (a>1) 0
#else 1
#end
#end

'Cause if it does, changing it to

#macro Stuff(a)
#if (a>1) #local toreturn = 0
#else #local toreturn = 1
#end
(toreturn)
#end

will remove the problem.

  I don't. Which version of POV-Ray are you using?

#macro N(D)#if(D>99)cylinder{M()#local D=div(D,104);M().5,2pigment{rgb M()}}

Amazingly enough, that does fix the problem! I don't know why the first way
doesn't work and the second one does, but hey, I'm happy now. Thanx!
