The efficient implementation of wait statements

This paper gives an overview of some of the factors that determine the efficiency of differently implemented wait statements. The purpose is to give some guidance to simulation modelers as to what system to choose and, for the chosen system, what wait constructs to use in order to make program execution efficient. It is also aimed at informing constructors of simulation software about what issues are important when implementing these statements. In particular, it presents some brand new features that can speed up the execution of wait statements, in particular in some versions of GPSS
