Abstract-syntax

Abstract syntax of Imp.

We formalize Imp's arithmetic expressions, boolean expressions, and commands, as free algebraic fixtypes.

Subtopics

Aexp
Fixtype of Imp arithmetic expressions.
Bexp
Fixtype of Imp boolean expressions.
Comm
Fixtype of Imp commands.
Comm-list
Fixtype of lists of Imp commands.
Command-fixtypes
Mutually recursive fixtypes for Imp commands.
