Concrete Data Structure
(CDS) A model of programming language terms developed in the
context of constructing fully abstract semantics for
sequential languages. A CDS is a 4-tuple (C,V,E,|-) where C
is a cell, V is a value, E is an event and |- is an "enabling
relation". An event is a cell and a value. A cell C is
"enabled" by a set of events S if S |- C. A state is a set of
events which are consistent in that the values they give for
any cell are all equal. Every cell in a state is enabled.

algorithms: the kernel of applicative language CDS", Algebraic
methods in semantics, CUP 1985].

concrete syntax
<language> The concrete syntax of a language including all the
features visible in the source program such as parentheses
and delimiters. The concrete syntax is used when parsing
the program or other input, during which it is usually
converted into some kind of abstract syntax tree.
Compare: abstract syntax.
