The debug plug-in is an optional part of the Kobol compiler. The plug-in must be installed before any debugging options will be enabled.
The debug plug-in comes in the form of a library. The directory where plug-ins are installed must be declared using the '-p' option when the compiler is invoked.
For example, if the plug-in is installed in '/usr/lib' then debugging can be enabled with the following command:
cob2c -p /usr/lib -g source_file
