%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
   also reported.
