Pascal language data structures

Much of numerical computation in chemistry revolves about numerical multilinear algebra. By this term I denote the manipulation of arrays whose dimension may exceed two. Mindful of Richard and Ledgard s admonition (16) that language design should never be overly ambitious, I propose only data structures, operations, and syntax for programming multilinear algebra. Multilin exceeds Bohlender s Pascal extension in two ways its provision for more than two dimensions, and its explicit declaration of data representations. 

Other applications call for more complex data structures capable of storing and handling vast amounts of information such as the properties of a group of similar substances and compiling literature data available on a given technique. In these Instances, languages such as PL/1 [24] or PASCAL [25] are to be preferred to BASIC or FORTRAN. 

On the logical layer, concerned with the data structures in CAD system data bases, a language similar to data structure declarations in Pascal is used.
