Hello,

I am trying to do some calculations in loops and everytime I calculate something it is written in the file but I don't want this, so how can I suppress it?

Example:
«var n = -1»
«FOR i: p.list_item»
   «n=n+1» «««I dont't want this calculation in my outputfile
   ««« more stuff...
«ENDFOR»


Thanks for any help
Liroth

e.g. «n=n+1;""» or you move the inc to a void method

if I try: «n=n+1;""» I get the error: " no viable alternative at input ';' "
how do I increase n in my loop without returning something from the called void function? is there something like a pointer from C which I can use in the function calling?

btw depending on what you want to do it may not be neccessary todo the looping within the template at all but in normal xtend code.
