A fortran programmer's introduction to simscript ii

This study is intended to introduce the FORTRAN programmer to some of the main concepts and features of the first three levels of SIMSCRIPT II--the levels which constitute an algebraic compiler. Emphasis is on the power and flexibility that SIMSCRIPT gives the programmer. Among the distinctive features are (1) the SIMSCRIPT preamble; (2) the preamble statements, such as NORMALLY, DEFINE, DEFINE TO MEAN; (3) the fact that any number of conditional expressions can be executed if a logical condition is met; (4) the ability to reread the same records in different formats. Unlike FORTRAN, SIMSCRIPT passes argument values rather than argument locations between subprograms. The method of constructing arrays is radically different. The SIMSCRIPT programmer can conserve core storage, construct ragged tables, generate tree structures, and do list processing with relative ease, and his programs can be read rather than deciphered.
