A Data Acquisition Command Interface Using VAX/VMS DCL

The user interface to a data acquisition system is being developed at the Los Alamos Weapons Neutron Research Facility using the VAX/VMS command language interface DCL. Commands are being implemented which provide for system initialization and control functions and FASTBUS diagnostics. The data acquisition system incorporates the concept of a data acquisition "state" (running, halted, etc.) where a certain subset of input commands is allowed.
