It is desirable that the main component of a simulation model, i.e. the "simulation" block instance, should respond to the sequencing procedures of 12.4 as if it were itself a process object. This is accomplished by having a process object of the class MAIN_PROGRAM as a permanent component of the quasi-parallel system.

The process object represents the main component with respect to the sequencing procedures. Whenever it becomes operative, the PSC (and OSC) immediately enter the main component as a result of the "detach" statement (cf. 7.3.1). The procedure "current" references this process object whenever the main component is active.

A simulation model is initialized by generating the MAIN_PROGRAM object and scheduling an active phase for it at system time zero. Then the PSC proceeds to the first user-defined statement of the "simulation" block.
