Abstract
This paper introduces an imperative process algebra based on ACP 
(Algebra of Communicating Processes). 
Like other imperative process algebras, this process algebra deals with 
processes of the kind that arises from the execution of imperative 
programs.
It distinguishes itself from already existing imperative process 
algebras among other things by supporting abstraction from actions that 
are considered not to be visible. 
The support of abstraction opens interesting application possibilities 
of the process algebra.
This paper goes briefly into the possibility of information-flow 
security analysis of the kind that is concerned with the leakage of 
confidential data.
For the presented axiomatization, soundness and semi-completeness 
results with respect to a notion of branching bisimulation equivalence 
are established.
