defines processing which takes place during the item selection process and during data input and output.

Codes in the 'correlative' attribute of the file-defining item are processed at filetime. Available codes include subroutines calls, bridge correlatives, id assignments, update stamps, and indices.

Codes in the 'correlative' attribute in the attribute defining items are processed during input and output processing.

Many processing codes can be called on the 'output-conversion' attribute of the attribute-defining item, including Pick/BASIC subroutines. See the related subjects for a complete list.

When an item is filed using the Update processor, all processing codes defined in the 'correlative' attribute of the file-defining item are processed. Items which are not filed using the Update processor use the bridge, index, and callx processing codes only.
