Can you pass a parameter to a subroutine, preferably a string, but also an object?

For string I have a simple solution:

...
: set_string var = "test_var"  text = "some val" ;
: gosub "my_sub" ;
...
my_sub : subroutine {
    : if (test_var == "some val" ){
        ...
    }
}

Probably for objects it only can be if-elseif-else block in the subroutine.

That's what I'm doing at the moment and I think that's the only way you can do it, but it sure would be nice if you could say something like:

: gosub "my_sub" param = "some val";

Then in the subroutine, you can use:

my_sub : subroutine {
   :if (param == "some val") {
      ...
   }
}

Saves a lot of typing and avoids having to declare a global variable just for the subroutine.

Agree, it would be cool. But we have what we have)

You never know. There are all sorts of undocumented things tucked away in Adventuron.

Not a hidden feature. It's a future feature though.
