Hi Ben,
I generally have used the File Type Nested command or the Input Program
command to utilize REREAD's or DO IF's to read a variety of nested
hierarchical files. Note that quite a few of the US Federal government
agencies that put out public data employ a nested hierarchical file
structure. As an example, consider the following schema:
Household record
Person 1
Person 2
Motor vehicle 1
Person 3
Motor vehicle 2
Accident information
Motorcycle 1
As you can see, keeping what links to what can become complex, but this
structure allows for a richer amount of data to be given out to the public
for further exploration and use. In this particular example, one can see
patterns of vehicle usage by multiple persons within the particular
household unit. By examining these types of linkages, much more
analytical information can be explored than is typically done with simpler
file structures.
Hope this is helpful.
Marshall

Thanks for the information!
Do you extensively use the complex files features of SPSS? At one point
PSPP had an implementation of REPEATING DATA, which I've meant to restore
sometime, but PSPP has never implemented the other complex files features.
