Hello,


Yes, this works well for functions.
But what about macro in parameter of a macro ?


I explain what I want to do :

* I have several macros :

#macro M1 (a,b,c) ... #end
#macro M2 (a,b,c) ... #end
#macro M2 (a,b,c) ... #end

 * And an other :

#macro MACRO (V1, V2, Macro)
  #local X = ...;
  #local Y = ...;
  #local C = ...,
  Macro(X,Y,C)
#end


I'd like to be able to give at MACRO, M1, M2, ... like that :
MACRO (P, Q, M1) or MACRO (R, S, M2)


Parse_String(String) doesn't seem to be usable, but I'm not sure I
understand how it works ;)
