Report Indexes

Indexes are defined using the DO INDEX statement in the Report Decollating Mission Definition screen (option R in the IOA Primary Option menu).

An index definition is in one of the following formats:

• LINE
• VAR

A LINE format index definition consists of the following:

• a specified line
• a column specification, which must be one of the following:
  • a specified column range
  • a column relative to the column identified by the mandatory MASK value
• an index type

A VAR format index definition consists of the following:

• a specified variable
• an index type

There are three index types

• Page Level – Every page of the report can be indexed by one value. Page Level is mandatory in a VAR format index definition.
• Record Level – Every line of every page in the report can be indexed by one value.
• Continuous Record Level – Identical to record level except records without an index value are indexed by the last previous value found for this index.

During the report decollation process, values for each index are extracted as a text string, either from the lines on the report page or from a specified variable. These index values enable users to determine if desired information is available, and to retrieve only the desired information for online viewing or printing.
