Continuous system simulation language is a non-procedural programming language. The written order of the statements bears no relation to the execution order. The statements must be sorted (or re-arranged) automatically by the compiler so as to generate the object codes with correct executing order. Based on analysing the characteristics of the dynamic section of simulation programs, the algorithms of auto-sorter implemented in the simulation language PARCSSL compiler of the software for parallel simulation PARSIM are given in this paper.
