FOSPRA, a language for forms and its implementation in the data recording systems REDAS

The language for forms, FOSPRA, is used for checking the input of data by means of forms using alphanumeric displays as the input devices. This checking can be done either on the bases of formal or of semantical criteria, with a pre-defined syntax. It is also possible to have results computed and to entry in output domains of the forms. REDAS offers, together with its driver, a comfortable real time data recording system.
