Extended FORTRAN for Process Control
M. Mensh, Wanderley Diehl · IEEE Transactions on Industrial Electronics and Control Instrumentation · 1968
Real-Time Fortran IV, the process control language used by Honeywell's Computer Control Division, is described. This language consists of the standard USASI Fortran IV with syntactical extensions that allow process control problems to be stated entirely in compiler language. The description deals mostly with the extensions and the reasons for their inclusion. An example program is appended.
