Automatic Editing and Error Handling › Automatic Editing Criteria › Overview

Overview

• An internal picture describes the format in which data for a field is stored in the user buffer.
• An external picture describes the format in which data for a field is displayed on the operator's screen.
• An edit table optionally defines a set of valid or invalid values or ranges of values for a field.
• A code table optionally defines values for encoding and decoding data.

External pictures can be defined by using the online or batch compiler as well as IDD; internal pictures, edit tables, and code tables are defined externally to the mapping facility.
