Double-clicking on the !ModInfo icon opens a window listing all ROM modules, along with their current status (running, active, dormant or unplugged). Clicking on a module's status changes it from active to dormant to unplugged and back to active (you cannot change the status of a running module).
Clicking on a module's title opens a window containing the module header information. Clicking on the 'Command keyword table' entry opens a window listing all of the commands recognised by that module. Clicking on any of the three SWI entries opens a window listing the SWI prefix and any SWIs recognised by the module.
Closing the window containing the module list terminates the program.
Full details of the module header format are given in the Programmer's Reference Manual.
