SOLVED - Hide return value of a function
 
I am using the following code:

#show %additem("north", path)

I do not want the return value to be sent to the mud that is why i use #show, but my question is can i use something else to just ignore/hide the return value?

Typically you would use #call for that, but in this case, that would have no effect. The %additem function doesn't actually change the contents of the variable, so normally you would assign the return value from the function back to the variable. Something like this:
Code:
path = %additem("north", @path)

Yeah I didnt notice that at first, code updated to the following and now all is working:

Code:
#var path %additem("north", @path)

%additem doesn't modify the list but does return a value.
#additem does modify the list but does not return a value (but note that #additem has the name of the list first and thing to add second, vs the function %additem which does the reverse)

#additem path "north"
is simpler and arguably more to the point of what you want to do.
