A compact reference listing of the syntax and semantics of SIMSCRIPT II, designed for professional programmers already familiar with the language. (SIMSCRIPT II is fully described in R-460, and its IBM 360 implementation in RM-5777.) The notation employed was chosen for convenience and descriptive power from conventions previously used in computer programming language descriptions. The study describes notation; basic constructs (symbols, primitives, metavariables); statements (non-executable, storage allocation, computation, control, input-output, simulation); system-defined values (constants, variables); a system-defined routine (the ORIGIN routine for simulation time); generated attributes, variables, and routines; and library functions.
