Pascal: Pascal Turnkey

Create a Pascal Turnkey system by transferring the desired program code to
the boot diskette and changing its name to System.Startup. When no file by
that name is present on the boot volume, the system defaults to the command
line.

To execute the System.Startup code from the command line, type X (for
execute), and then

SYSTEM.STARTUP.

The final period prevents the operating system from appending the .CODE suffix
to the file name before trying to execute it.
