The PRINT variable command displays the value of a specified variable.
The value is displayed in the form of an assignment command for that variable.
Some variables that can be changed with ctl do not appear on any of the ctl output
screens. To see a listing of all variable names, use the
print all command.
For example, if you type the following two variables
> print minimum node action;fsg cache percent
then the following might be displayed, depending on your system:
Minimum Node Action=Clique-Down
FSG cache Percent=80
