Data management/Data files

A data management tool called 'Expand' in Instat (included in the companion GenStat Discovery CD under 'University of Reading (SSC).) may be used where necessary to link the HOUSEHOLD and PRODCAT records stored for the different homesteads (see section 9.6 of the Instat+ Introductory Guide).

GenStat also has a similar facility to link and merge records from different files. The 'merging' or 'expansion' is done through common key or index variables that appear in both files. Of course, the merging can also be done in Access itself.
