[ACT-R-users] RPM 2.1.1

[Mike Byrne]

There's a new version of the RPM stuff available, version 2.1.1.
Available from the usual place:

http://chil.rice.edu/projects/RPM/download.html

If you use the perceptual-motor components more than trivially, I'd
recommend picking it up.  Also, this is important for people
running MCL 5 under Mac OS X, as it solves the cursor movement
problem.

For the interested parties, the release notes are appended at the
end of this message.


Enjoy!
-Mike

VERSION 2.1.1
* Released Feburary 7, 2003. 

* Added ASSIGN-FINST action. This allows a finst to be assigned
without the actual location being attended, which is something that
several people have asked for. Works like this on the LHS:

+visual>
  isa       assign-finst
  location  <loc>

where <loc> is a chunk of type visual-location. You can also do it
by object, like this:

+visual>
  isa       assign-finst
  object    <obj>
  
where <obj> is visual-object chunk (or a subtype). [Someone is
going to ask what the evidence for this ability is. I'm going with
Pylyshyn's ideas here.] 

* Made some small corrective changes in the logic of updating
attended locations. 

* Dan fixed various symbol and other issues with ACL. 

* Each module now has its own version number. 

* Fixed how RPM accesses ACT-R chunks to make it more robust. Also,
updates the module state chunks much less often. 

* It now moves the cursor around properly under OS X. This involves
the "cfmbundle.lisp" file.
