A user's and programmer's manual for SIMSCRIPT II that requires only a basic knowledge of computers and programming language translators (compilers). Sections that are unusually difficult or contain features of limited use are marked with an asterisk. The manual is divided into five chapters, corresponding to five language "levels." Level 1 is a teaching language designed to introduce programming concepts to nonprogrammers. Level 2 is a language roughly comparable in power to FORTRAN, but departs from it in specific features. Level 3 is comparable in power to ALGOL or PL/I, but with specific differences, and contains information on the new ALPHA mode for alphanumeric manipulations, on writing formatted reports, and on internal editing. Level 4 contains the entity-attribute-set features of SIMSCRIPT, which have been updated and augmented to provide a more powerful list-processing capability. Level 5, the simulation-oriented part of SIMSCRIPT II, contains statements for time advance, event and activity processing, generation of statistical variates, and accumulation and analysis of simulation-generated data. Two new debugging routines, BEFORE and AFTER, enable the monitoring of six complex processes.
