HYDRA on the Rutherford Appleton Laboratory Central Computing System (Second Edition)

摘要

This report completely supersedes the report 'HYDRA on the Rutherford Laboratory Central Computing System' (RL-80-036). It is required principally because there is a new loading procedure with the current release of HYDRA 3.32/1. The new release is now available on the R. A. L. central computers, and all the necessary information to use it is given here. HYDRA is a system which gives the Fortran programmer facilities for the creation, structuring and management of data banks in a dynamic way within BLANK COMMON. It also provides facilities for structuring a program in units consisting of groups of subroutines. In addition, there are many supporting functions, including the handling of 'title' data, facilitating the input and output of data structures, recording condition codes, printing selected data banks, providing a comprehensive set of line-printer histogramming and plotting routines, extending the effective size of available memory by the use of backing store, and simplifying the tracing of coding errors by means of debugging aids.
