NCL Debug Facility

The NCL Debug facility is made up of a set of commands that allow you to do the following:

Start and stop an NCL debug session
Control the execution of NCL processes
Display and modify the contents of NCL variables, independent of the nesting level of the process
List the procedure and subroutine nesting levels
Display the source code that is being executed (not the source currently on disk, that is, without comments or indentations)
Receive NCL trace output at another region, thus being able to view the trace output concurrently as the debugged process executes
