SIMON (Batch Interactive test/debug)
From Wikipedia, the free encyclopedia
SIMON (Batch interactive test/debug) was a proprietary test/debugging toolkit for interactively testing Batch programs designed to run on IBM's System 360/370/390 architecture.
It provided Instruction step, conditional Program Breakpoint ("Pause") and storage alteration features for Assembler, COBOL and PL/1 programs. High level language (HLL) users were able to see and modify variables directly at a breakpoint.
It additionally provided features to prevent application program errors such as "Program Check", "Wild branch" , and Program loop. It was possible to correct many errors and interactively alter the control flow of the executing application program.
