Backing store

is a system provided by Genstat for the convenient storage of data structures and procedures. The OPEN directive allows you to open a backing-store file, the STORE directive stores information and RETRIEVE allows you to access it later on (perhaps in a subsequent run of Genstat). When a data structure is stored, Genstat keeps not only the data values but also all the other associated information (for example level and label definitions of factors, sub-structures of pointers and so on).
