Jconsole is the non-GUI interface to J. You type in sentences and J types the results. You have access to all the features of the J language.
Even if you use a GUI as your normal interface to J, you will occasionally need to use Jconsole to update the GUI itself.
To start Jconsole, either
- use the desktop shortcut, if you installed one, or
- navigate to your_J_installation_directory/bin/ and launch the Jconsole task
Unix jconsole uses editline. The input history from previous sessions is loaded from file ~/.jhistory (if it exists) when jconsole starts and the new input lines are added to the file on exit.
