<DIV><FONT face=Arial size=2>I see that a) Lisp can run experiments and b) you
can use !output! in a production to print something to the computer
screen.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>1) Can a Lisp variable be set in an ACT-R
production so that Lisp later has access to it - something like:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>LHS</FONT></DIV>
<DIV><FONT face=Arial size=2>==></FONT></DIV>
<DIV><FONT face=Arial size=2>(setf *foo* =num1)) ;where *foo* is "global" so
Lisp has access to it</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>or</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>LHS</FONT></DIV>

<DIV><FONT face=Arial size=2>(setf *bar* =str1)) ;to pass a string to
Lisp</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>2) Can a Lisp function be "fired" from a
production - something like:</FONT></DIV>

<DIV><FONT face=Arial size=2>(DoSomethingUsing =num)) ;for example to
execute some calculation using =num</FONT></DIV>
