6. A computer program product for setting a stack pattern breakpoint for a COBOL program, the computer program product comprising: a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising: providing a static program control flow view of a plurality of COBOL paragraphs of the COBOL program; enabling a user to select the stack pattern using the static program control flow view of the plurality of COBOL paragraphs of the COBOL program; and setting the stack pattern breakpoint in source code of the COBOL program using information from a compiler compiling the COBOL program to create a pseudo-stack that can be operated on by a debugger to evaluate stack pattern conditions for the plurality of COBOL paragraphs, wherein setting the stack pattern breakpoint further comprises finding a perform save cells section using the information from the compiler to find a plurality of save cells, scanning the plurality of save cells and associating each of the plurality of save cells with at least one of the plurality of paragraphs, and, responsive to a perform being executed, modifying at least one of the save cells to point back to the perform save cells.
7. The computer program product of claim 6 , wherein the method further comprises: enabling the user to modify the stack pattern breakpoint using a user interface control.
