Shebalin, Paul "TRIDENT Higher Level Language Syntax Definition" Naval Surface Weapons Center Dahlgren VA Nov 79 NSWC/TR-3914 view details Abstract: This document presents a complete and rigorous syntactic definition of the TRIDENT Higher Level Language (THLL). Two different formulations are included: syntax graphs and productions. The syntax graphs provide a visual aid to quickly determine the struct re of all THLL constructs. The productions express the syntax as it is used, essentially, by the compiler. The TRIDENT Higher Level Language (THLL) is a procedure-oriented programming language for use in writing software programs for the TRIDENT Digital Control Computer (TDCC). this computer is to be used in the Mk 98 FCS and the Mk 88 Mod fire control system (FCS).
