Input Buffer

CA Culprit places input data in an area called the input buffer. If a single input file is read, the buffer contains a single occurrence of an input record. If multiple input files are read, the buffer contains one record from each file.

During the extract phase of CA Culprit processing, the input buffer is processed by each report in the run, as shown in the following figure. Type 7 process parameters process the data contained in the input buffer; type 5 edit parameters extract the data contained in the input buffer. The extracted data is stored in an extracted items and statistics file.

After the input buffer passes through the type 7 logic of each report, it is filled with the next record or records and is processed by each report in the run. This cycle continues until an end-of-file condition occurs. At end-of-file, the extract phase is completed.

Note: The input buffer is processed by one report at a time; type 7 process parameters process the contents of the input buffer and type 5 edit parameters extract the contents of the input buffer to the extracted items and statistics file.
