Method, system and program products for screening a program of a computing environment for debug processing are presented which employ a table that contains information identifying at least some program areas of storage of the computing environment where programs to be debugged may reside and information identifying programs of the computing environment to be excluded from debugging. After detecting a debug trigger point during execution of a program, screening is accomplished by referencing the table to first ascertain whether the trigger point is within a program area of storage meaning that the program under execution may comprise an application program to be debugged, and if so, referencing the table to determine whether the program has been explicitly excluded from the debug processing. If not excluded, debug processing may proceed.

Facility for evaluating a program for debugging upon detection of a debug trigger point

A program having a plurality of concurrently executing versions is debugged. A version of the program to be debugged is selected from the plurality of versions of the program, and that selected version is debugged. As one example, the selection is responsive to the receipt of at least one task of the computing environment that is associated with the version to be debugged. The debugging of the selected version does not affect other versions of the program, other programs executing within the computing environment or other tasks using that version.
