It includes all relevant material from prior releases and also describes the new features of this release. The User's Guide does not explain each feature of the OS in detail; instead, it explains operations such as installing and booting the system, and presents the details of the Command Shell and Filer commands (see the Operating System Reference Manual for a complete description of the Operating system). Because the Operating System Reference Manual is not updated for each new release, the User's Guide also contains explanations of any new features or calls that may not fit into the above topics. The User's Guide assumes that the Operating System Reference Manual that you have is dated March 1, 1982. This release of the Operating System boots from a Profile or Twiggy rather than the'Apple II.

Therefore, readlns and writelns can only be seen on your Soroc~ WARNING: YOU NEED A SOROC, TO USE THE STANDALONE OS! Attach the So roc to channel A of the Lisa; this channel is the second from the left when you are standing in front of the system. When the OS boots from a Profile, that Profile must be attached to the parallel port (the connector farthest to the right when viewed from the front). This port is 'PARAPORT' to the OS and '&3' to the Monitor. Your other hard disks are attached to the N-Port card, which must (for now) be in Slot 2 (the middle slot). Starting from the bottom of the N-Port card, the ports are named '&4', '&5', and '&6' by the monitor, and 'SLOT2CHANl', 'SLOT2CHAN2', and 'SLOT2CHAN3' by the as. The monitor gives preference to disks attach…
