Abstract : A set of FORTRAN-compatible primitives written in IBM 360 assembly language allow the user to develop file-based information structures for applications programs operating on small computers or partitions. Files may reside on disc or magnetic tape and are retrieved and swapped in overlapped mode during program execution. For programs operating in overlay mode performance deterioration due to data retrieval is less than three percent. (Author)
