The i processing code is stored in the correlative (attribute 8) of the file-defining items to maintain index keys. The root FID (VME only) is inserted by the system and must not be altered.
|Code Type||File Defining|
|sub.code||C||Indicates a case-sensitive index.|
|N||Indicates a numeric index.|
|root.fid||Beginning (FID) address of the index.|
|a.code||Defines the method by which the index keys are generated. It must be a valid a processing code and reference at least one attribute count within the file. Translates should only be used in accordance with the s (subindex) processing code.|
When an index is created using the create-index command, the system inserts the i code in attribute 8 of the file-defining item along with the root FID and the a processing code.
If data is present and the index processing code is added directly to the file-defining item, the pre-existing items are not added to the index until they are filed. Any new items or pre-existing items that are subsequently filed are automatically added.
If data is present and the create-index command is issued, the file-defining item is automatically updated with the index processing code and added to the index. During the creation of the index, a counter displays on the screen indicating the number of items added to the index.
