Debugging Assembler Applications

Restriction: The MFASM debugger is unable to open a window for debugging on any enterprise server region started via ESCWA, as Microsoft has permanently disabled access to the user desktop from any application started in the background and owned by "SYSTEM".

You can debug Assembler and Assembler/COBOL applications using the Assembler Debugger. This debugger appears in a separate window, outside of the IDE.
