Editing techniques
When you attempt to edit a data set, File Manager examines your editing options, data set type and size, and uses one of three main variations of editing technique. Although these techniques should be virtually transparent to you, they are explained here.
The type of edit taking place is visible during
the editor session by a
denotation in the top left of the editor panel title line:
- Edit
- Denotes a full edit (that is, including the ability to insert and delete records, and the ability to copy and move records).
- Aux Edit
- Denotes
a full edit (that is, including the ability to
insert and delete records, and the ability to copy and move records)
where File Manager is making use of a secondary file to enable the
edit.
See:
- Inplace Edit
- Denotes that records may only be updated in place, and that the ability to insert or delete records is not available.
If you do not need to insert or delete records, you can improve the performance of the Edit session (especially when working with large files) by selecting the Inplace edit option. This avoids the associated delays of copying to and from an auxiliary file.
Note: Unless
the text in other sections of this chapter explicitly refers to one
of these editing techniques, the information in this chapter applies
to all
editing techniques. Differences between In-memory, Auxiliary, and
In-place
editing are highlighted where applicable.
The following sections describe the different editing techniques.
