What You Can Debug
The CA IDMS online debugger is an interactive facility used to detect, trace, and resolve programming errors in programs that run under the control of DC/UCF. The debugger can be used with these load modules:
For more information on using the debugger with Assembler, COBOL, and PL/I programs, see Aids for Debugging Assembler, COBOL, and PL/I Programs.
How You Use the Debugger
You use the online debugger to:
The online debugger receives control when your program abends (for example, with a data exception). You can then determine the abending instruction and examine program variable storage to determine the error.
To trap logic errors, set breakpoints that halt program execution at a specified line number. The online debugger receives control when your program reaches that line number, so that you can examine program variable storage.
