Accelerate Native Sort Calls
You already know that IRI CoSort is faster than your compiler's built-in sort function. Do you know how many methods in the CoSort package improve COBOL sort performance? See:
Generate Reports from COBOL Files
CoSort's Sort Control Language (SortCL) Program not only converts, transforms, and protects COBOL files and data types, it can produce custom detail, delta (change) and summary reports. SortCL has a wide range of built-in reporting and display functions similar to those in IBM's COBOL Report Writer and ICETOOL.
SortCL uses a simpler 4GL to define data sources, manipulations, and target layouts. See:
For those with a sophisticated business intelligence platform, like Cognos or Business Objects, CoSort's SortCL tool is commonly used to prepare (or "franchise") big data for them. SortCL filters, converts, sorts, joins, aggregates, and reformats COBOL files into smaller CSV or XML subsets (or "feeds") that the BI tools can handle. This removes the overhead of "big data" transformation from the BI layer, and the data and coding redundancy that goes with it. See:
