The methodology of static analysis was used to examine a suite of programs for psychophysiological data processing, with a view to specifying useful features for a specialized computer language. Obtained results showed that facilities often ignored in conventional solutions were important. The need for advanced data structures, similar to Pascal, could be shown, but equally the requirement for compatible data operators, capable of transforming arrays and structures, was demonstrated. Input/output was of major importance, and not only at the language level. A clear definition of terminal, record and random access I/O was needed, and some control of the interface to the operating system and machine environment was also desirable. Traditional emphasis on control structures in languages was shown to be misdirected, as the simplest of FORTRAN control statements produced a well structured program. And finally, it was shown that good systems design in a sympathetic software environment could reduce assembly language coding requirements, whilst preserving the execution speed of machine code. Altogether, the results of the static analysis recommend that any language for psychophysiological computing be firmly based on an ecological survey of data processing requirements.
