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).
