of CMS in VM/PC is less complex, and allows you to
tailor your CMS environment for special requirements
you may have.
• Screen format
The screen format of VM/PC is similar to that of
VM/SP Release 2, although it is not identical. The
scroll field at the bottom right of the screen allows you
to scroll back through the contents of the terminal
history buffer. In addition, VM/PC has two additional
options on the CP TERMINAL command, which allow
you to control the action of the P A2 key and the display
of information lines longer than the width of the screen.
Also, the VM status area on the lower right of the screen
differs from that of VM/SP Release 2. It will indicate
'Waiting' when the system is not actually doing work for
you and is waiting for you to enter a command. The
CMS prompt 'Ready;' is also slightly different than that
ofVM/SP.
CMS messages
Most messages VM/PC CMS will display to you are in
mixed case, unlike the messages displayed by VM/SP.
In addition, the text of these messages comes from a
system message file which is on the S-disk.
Commands do not support tape drives, virtual readers, or
punches.
The support for these devices is not present in VM/PC,
and commands which support these devices are not
present.
• IDENTIFY command output
Since there is no RSCS virtual machine on your
VM/PC, the fields in the IDENTIFY command output
which indicate node and userid of the RSCS virtual
machine are filled with token placeholders of
'*'.
Also,
since you set the timer of your VM/PC, the time zone is
designated as 'LOCAL' in the command output.
