Here is an easy but powerful way to use CM evolveIT to identify potential bottlenecks in your COBOL system using a simple regular expression search.  Multi-level looping structures are an instance where performance issues might be found.  Identifying these can be difficult since a traditional mainframe scan doesn’t allow finding text on separate lines in the source.

In CM evolveIT, it is possible to use the Text Search tool along with a Multi-line search to find this kind of code construct.

Use the screen shot below to see how to set up this kind of search by using the multi-line search option, searching Original Source and programs only, with a simple regular expression: 

“perform varying.*perform.*until”.

Try the search and let us know what you find as opportunities for improvement in your system.
