Top Down Logic Progression and Bottom Up Logic Regression Tool (FLHCOTOP)

The Top Down Logic Progression and Bottom Up Logic Regression Tool display the logic progression and regression of a COBOL program.

The Top Down Logic Progression Tool displays the progress of logic of a COBOL program from top to bottom. It does not show the conditions that cause the PERFORM of a subordinate paragraph.

Instead, it functions like a cross reference listing, except that it allows you to familiarize yourself with the program without constantly referring to the cross reference listing. It gives you a bird's eye view of logic progression.

The Bottom Up Logic Regression Tool displays the path of how a program arrived at a certain point in the program. This is an ideal tool to identify a problem.

You start at the paragraph where the problem occurs and continually track the logic backwards to the point where the problem was created. This eliminates the need for frequent references to the Cross Reference Report with no need to mark your place at relevant pages in the Cross Reference.
