Command cruising Definition/Update Processor
Applicable release versions: AP
Category Update Processor (113)
Description ability to scan forwards and backwards through items in a file.

Cruising on a local file using the file index provides the ability to move from item to item in the current file. In the Update processor, "<ctrl>+f" moves "forward" to the next item in the local index and "<ctrl>+d" moves "backward" to the previous item. The terminal "beeps" when reaching the beginning or end of the index.

A "remote" index provides the ability to logically link a "remote" file to the current file with the capabilities of performing the following:

"table lookup"

To perform a "table"-like lookup of items in the remote index using either a full or partial key, enter the key followed by a "<ctrl>+u" to call up the first match. If no match is found, the next item in the remote list is called up.

"table forward"

To move "forward" to the next item in the remote index, enter a "<ctrl>+u". The terminal "beeps" when reaching the end of the remote index.

"table backward"

To move "backward" to the next item in the remote index or file, enter a "<ctrl>+y". The terminal "beeps" when reaching the beginning of the remote index.

"zooming"

To enter or jump into the remote file using the currently displayed reference point, enter a "<ctrl>+g".

"item binding"

To file or store any "link" modifications to the current item, including changes in its "remote" references that might have occurred using one of the above commands, enter "<ctrl>+xf". (See also "bridges", for maintaining automatic two-way referential integrity.)

A classic situation for using remote indexes, for example, would occur while entering an order item; the order file would likely be linked to an inventory file, and the operator could both "lookup" and/or "table" through the data in the inventory file until the desired item is located. If need be the operator could "zoom" over to the item in the inventory file and examine or modify it, and then return to the current order item. When finished with the order, the operator merely files the item and all its line-item references would be maintained with the order.

Note: There is no restriction from the "remote index" being used on the same file that the current item is also residing in. This would be typical in files where an explicit hierarchy exists between items, such as a "parts.master" file which has a bill of materials, an "entity" file which has both companies and employees, or a "projects" file containing sub-tasks, etc.

"Double-clutching" is a term given when a field contains both a local and remote index. An example of this is using the order example mentioned in the previous paragraph. In addition to the "remote" index to the inventory file, a "local" index could also exist to find the next item in the order file that had ordered a particular inventory item.
