TADS Help - Error Messages

                          From Sue

When you compile and run TADS adventures, there are a range of
error messages that you can get. Some are easy to understand such
as 'missing semi-colon'. Others are very confusing, such as
'object value required'. What I will do in this file is list some
of the ones which have thrown me, saying when I got them and what
I did to get rid of them!

1. TADS-1010: object value required

I got this message during playtesting when the player was trying
to go through a door which was currently shut until the player
solved a problem. What I had forgotten was to add the line

return(nil);

Even though the player hasn't moved, you must add this line.

2. TADS-1026: wrong number of arguments to user function.

Again, I got this during playtesting. When you write your own
verb, you have to put (actor) or (actor,dobj) in the method code.
I'm never sure which of these to put, I haven't sussed the logic
behind it! If you get it wrong, you get this message so just put
the other one - as you can see, my programming is still a bit hit
and miss.
