OOPAL stands for Object Oriented Programming and Array programming Language 
integration.  It is presently implemented in Objective-C as part of the 
F-Script dialect of Smalltalk for the Mac.

Array programming is a useful abstraction, particularly for numeric work, 
that is largely orthogonal to OOP.  Array programming methods allow 
extremely concise problem statements and solutions.  In the 1960's Ken 
Iverson created APL (http://sigapl.org) at IBM as a specification and rapid 
prototyping language.  Classic APL uses symbols to represent primitive 
operations and requires a special character set.  Modern APL variants J 
(http://jsoftware.ocm) and K/Q (http://kx.com) use one or two ASCII 
characters to represent primitives.  Some APLs have added OO features. 
OOPAL adds array programming to Smalltalk.

Here's a paper describing OOPAL http://www.fscript.org/download/OOPAL.pdf .
