%X A problem that occurs frequently during the development of
parallel programs is deadlock.In the domain of transputer
technology (and of parallel computing in general) run time
debugging software still is a problem. This increases the
value of verification tools based on static analysis, even
if the functionality is sometimes limited.In this paper we
present our approach to static analysis. The analyzer
reduces an occam program to the relevant actions hi the
context of this problem (communication, possibly through
guards: PAR constructions...), and subsequently examines the
program, reporting possible problems that could occur during
real execution. The tool goes beyond the purpose of
detecting deadlocks only: other infinite wait situations are
