An in – core batching standard fortran complier for large ICL 1900 machines

We are accustomed to thinking that the requirements of different users of FORTRAN (or any other language for that matter) are so varied that they can only be met by a series of compliers: a standard one, an optimizing one, an in‐core batching one and so on. This paper describes a complier which, although its main aim was to process batches of small student jobs, was desinged to compete with all the manufacturer's compliers on their chosen ground.
