Alias notes

[Anders Lassen]

I'm a student at Institute of Datalogy, Univ. of Copenhagen and work
on my thesis titled "animation coding for 3D Computer animation" or 
something like that. In danish "Bevaegelseskodning til 3D computer
animering" exiting and fun! But working with alias on a personal Iris 
has come up with some stupid bugs.

Alias is 3D comp. anim. software. It is a standard version of alias 2.4.1
without the special features, such af metamorfosis package and natural
phenomena procedures. Well here are my two bugs:

1. Envoking (starting) the sdl-editor causes the application to
   halt. Anyone know how to fix it?
	or is this a special feature of this version!

2. In the dope-sheet. deleting a key-frame is not possibel. My way is to
   create a new column, but this is not a solution. Occasionally
   the malfunction in dopesheet causes the application to halt.

In adition i want an answer as to how to create procedures of your own
in sdl. It would be of help to me to be able to take an seudo 
"object oriented" aproach to coding in sdl. You now, tying methods to objects.
The normal way is to implement a set of procedures, you invoke in a tidy way.
The parallel to sdl would be to make simple, tidy procedure and functioncalls
beside the geometry, while having the code in some include.

Also it would be a more general approch, as the code can be reused, 
and quickly referenced in newgenerated sdl code from the application.

One answer ofcause is that the sdl-interpreter "renderer" does not allow
procedure declarations in the syntaks. In other words only procedures compiled in the "renderer" an be invoked. An the whole sdl-kode is avaluated once every frame, so this is not a preprocessor problem.

If I'm wrong in some or part of this, I wan't your opinion.
