Réponse courte : non pas de pointeur au sens adresse mémoire indiquant 
la position occupée par la variable.


Réponse longue : Oui de manière /invisible/.


#macro foo(a)
   #declare a = a + 1;	
#end


#declare a = 1;	
foo(a)
#debug concat("a = ",str(a,0,0),"\n") // aka printf ("a = %d\n",a)

Affiche : a = 2

La fonction/macro foo() a modifier la valeur de la variable 'a'.


Comme dit la doc : "Les macros POV-Ray sont un mélange étrange de macros 
et de fonctions"
