CA ADS Batch extends the online concept of response fields to the batch environment. An input file map can include one or more external fields that make up the map's response field. On a mapin operation, the value of the response field helps to determine the next dialog response process or application function that is executed, just as in the online environment.
For example, an input record can have a response field whose value is ADD, MOD, or DEL. A dialog can be defined with one response process that is executed when the response field value is ADD, another when it is MOD, and another when it is DEL. The response process executed at runtime after the dialog performs a mapin operation depends on the input record's response field value.
Input Files with Multiple Record Layouts
Response fields are especially useful in accessing input files that have multiple record layouts, as described under "Application structure" later in this chapter.
