Halting SYSGEN Command Actions 

CTRL Y stops listings or cancels partially entered SYSGEN commands.

Issue the CTRL Y at any point in SYSGEN. SYSGEN terminates the current
action and returns its prompt.  If you enter CTRL Y while SYSGEN is
generating a boot tape, you have the option of terminating or continuing
the tape generation process.

CTRL Y is effective if the SYSGEN output and input has not been
redirected, and SYSGEN is being run from a session.
