Software documentation: PntDef

Preface

The primary description of all monitor and control points for the Compact Array are held in a set of files known as `The Database'. The database consists of a file, called the descriptor file containing the definition of all control and monitor points and a set of secondary files providing descriptive information on some points. The descriptor file contains a record for each type of point. Each record contains fields described the following FORTRAN structure held in A_DATA.INC PNTDEF now also writes its creation date into the PDEF record. This is so that the process CAMPA (Compact Array Monitor Point Archiver) will recognise any changes in the PDEF array. This is written in the last record that exists, thus making this useless for genuine monitor point data.
