A language for specifying the data acquisition and initial event rejection requirements of experiments using the new TRIUMF VAX-based CAMAC data acquisition system has been designed and implemented at TRIUMF. Terse, low level, assembler-like syntax for the language was rejected in favour of a form more familiar to physicists, namely FORTRAN. The language is known as TWOTRAN, and is an extended subset of FORTRAN. Users write TWOTRAN programs and compile them into PDP-11 machine code using the TWOTRAN cross compiler, executing on the VAX. Compiled programs are down-loaded for execution into a CES Starburst, installed in a HYTEC System Crate based CAMAC system. This paper describes the design of the language, from its earliest inception to its present state, and the interfacing of the language processing support system to the remainder of the data acquisition system.
