- Functional Scope of the Editors available in Predict

## Defining Editor Defaults

Specify your preferred editor in the Profile > Handling screen shown below. Since not every editor can be used for every task in Predict, and not every editor is supported in every environment, the editor that is actually called will depend on the function and your current environment.

For example:

- If you have the Software AG Editor as first choice and the Natural Editor as second choice editor, the Link Editor (a modified Natural Editor) will be called for the function Link children because the Software AG Editor cannot be used to edit a link list.

- The Software AG Editor will always be called to process the result of a retrieval operation, irrespective of the preferred editors specified in the screen below.

Note
It is recommended to set the editor preferences as shown in the screen above.

### Limited Checks with Word for Windows as First Choice Editor

If Word for Windows is specified as first choice editor, Predict only checks whether the connection from host to PC is active. This means that the Natural parameter PC is set to ON, either by

- specifying PC=ON when starting Natural or

- entering %+ in the command line of your Predict session.

If Word for Windows cannot be called for any other reason (for example due to an invalid task in Entire Connection or because workfiles are incorrectly defined), the function Edit description or Edit extended description skeleton will be terminated. Your second or third choice editors will not be invoked.

### Effects of Editor Defaults

The preferences specified in the Profile > Handling screen affect the following maintenance functions in Predict:

All object types | Edit description Edit default extended description
Extract | Edit/link objects Note For extract maintenance function Edit/link objects: If your first-choice editor is SAG or Word for Windows, the Software AG Editor is called as link editor. If your first-choice editor is Natural, the function Build/Extend an Extract is called.
Field | Edit field expression
File | Edit subquery of a file
Program | Edit procedure code of a program
Verification | Edit rule of a verification

## Calling an Editor in Predict
