In this example, the ZEX0902N NCL procedure is executed. The DEBUG START
command starts a debug session. The GO command resumes execution of the paused
NCL process. The DEBUG BREAKPOINT command sets a breakpoint at the following
positions: statement 16 in the top-level procedure; statement 1 of the LEFT_TITLE
function; the exit to every procedure or function; the variable &LINE for write access;
and at the termination point of the NCL process.
