On mainframes, sorting is one of the most important, and resource-intensive, data processing operations. Off the mainframe, high-volume data sorting is required of commercial Unix and Windows data centers involved in rehosting these applications, as well as database reorg and load operations, report generation, and data warehouse staging (ETL). In these cases, the robust, commercial-grade sort performance of the CoSort package is in high demand. To mitigate migration time as a factor in CoSort adoptions, IRI has developed a suite of tools to leverage your existing metadata or sort function interfaces.
The conversion tools provided by CoSort enable you to begin using its flexible and powerful Sort Control Language (SortCL) program, without rewriting your existing legacy sort scripts, or creating new ones. This document describes how to migrate from the syntax of legacy sorts to CoSort's advanced 4GL for data definition (DDL) and manipulation (DML), SortCL.
