ABSTRACT:
Control statements related to record input, output, filtering, and formatting in a data processing system are scanned by a parser to find one or more trimming control parameters referenced in the control statements. A record trimming module scans selected data records backwards beginning at the end of the record. A record length associated with a data record is decremented as trailing values that match a value specified in the trimming control parameters are trimmed from the processed records. Processed data records are output to a specified file. The present invention increases the efficiency of processing data records within data processing applications such as pipelined sort utilities.
