Hi Jaco
It certainly does.
Only stored fields can be indexed.
Indexing improves the speed which which certain functions takes place, for
example, finding and sorting, but at a cost of increasing the size of the
file and the increasing the time it takes to tab between fields. Fields
can be set to be stored or unstored, or can be set to turn indexing on
only if needed. When in doubt, the last option is the usually the safest
bet.
Fields which are formatted as pop-up lists which reference fields rather
than a static list of values must reference fields which can be indexed.
Hence, the values in those fields must be stored.
Some fields cannot be stored (Global fields, Container fields, Summary
fields as well as Calculation fields that contain references to Global
fields, Related fields, Summary fields, or other unstored Calculations
fields). Consequently, these fields cannot be used as value lists.
Some fields should not be stored, for example, Calculation fields which
use Status functions to reflect the changing status of many things, for
example, date, time, found count, record number, and so on.
