You can debug your programs at the machine interface (MI) level.
To debug your programs at the machine interface (MI) level, you can specify an MI object definition vector (ODV) number for the PGMVAR parameter of a command and MI instruction numbers for the STMT parameter of a command. For a breakpoint, the system stops at the MI instruction number just as it would at an HLL statement number. You must always precede the ODV or MI instruction number with a slash (/) and enclose it in apostrophes (for example, '/1A') to signal to the system that you are debugging at the MI level.
