'''CoSy''' is a stack-based APL influenced language written by Bob Armstrong of Coherent Systems Inc. CoSy is implemented as a vocabulary of defined words that extends Reva [[wikipedia:Forth (programming language)|Forth]] to provide [[array]] capabilities. CoSy has been re-implemented twice. The original implementation was in [[flat]] APL, the second in [[K]], and finally the current implementation in Forth.
 
== Features ==
CoSy has many major departures from the APL tradition: Most notably, it uses keywords for primitive functions.
 
All arrays in CoSy are simple lists. This makes it comparable to [[K]] and [[RAD]]. Similar to those languages, it also allows usage of functions as data using Forth's quoting.
