Standards: Accommodating standards and identification of programming languages

The user public wants standardization and reliable identification of programming languages and related services. One way of achieving these goals is illustrated by the methods adopted for TRAC T-64 interactive language, and its related family of languages. Oppressive rigidity usually associated with standardization is avoided by a new accommodation technique accessible to the user to allow local variations within the language. Explicit standardization of the language is undertaken at the organizational source of the language. Use of the organizational trademark (TRAC) on the published standards, and services relying upon them, provides a reliable public identification. These methods can be useful applied to other programming languages and computer services.

TRAC, a procedure-describing language for the reactive typewriter

A description of the TRAC (Text Reckoning And Compiling) language and processing algorithm is given. The TRAC language was developed as the basis of a software package for the reactive typewriter. In the TRAC language, one can write procedures for accepting, naming and storing any character string from the typewriter; for modifying any string in any way; for treating any string at any time as an executable procedure, or as a name, or as text; and for printing out any string. The TRAC language is based upon an extension and generalization to character strings of the programming concept of the “macro.” Through the ability of TRAC to accept and store definitions of procedures, the capabilities of the language can be indefinitely extended. TRAC can handle iterative and recursive procedures, and can deal with character strings, integers and Boolean vector variables.
