CONTROL
SEQUENCE
A control sequence is when you use the CONTROL key (sometimes
labeled CTRL) in combination with other keys to affect what is occuring
on your screen or during the execution of a command or program.
To use a control sequence, hold down the
CTRL
key and press another
key. One of the most common control sequences is Control-C, which is
used to interrupt commands and programs. To do this, hold down
CTRL
and press
C
.
Throughout this manual, we represent a control sequence by showing
the keys you press, like this:
press

DEFAULT When you leave information out of a command line, AMOS often has a
set of information it substitutes for the missing items. For example, if you
don’t tell AMOS what account a file is in, it usually assumes it is in the
account you are currently logged into.
Defaults vary among commands. Check the reference sheet for a
specific command to see what defaults it uses. In particular, the special
commands called wildcard file commands handle defaults differently than
other commands on the system.
DELIMITER A character marking a division between two pieces of data. For example,
in the date display 12/04/86, the slash "/" is a delimiter. A dash "-" is also
a common delimiter.
DISK DRIVE
CONTROLLER
A board or paddle-board containing the hardware interface between the
physical disk device and the Mass Storage Bus controller (for example,
the AM-515). The disk drive controller is specific to the type of disk it
controls. In this case, the disk drive controller is a Xebec, and is
"between" the AM-515 and the physical disk drive.
DISK FILE An area of memory on a hard disk containing a program, text, or data file.
Unless such a file is erased, it resides permanently on the disk.
DSK0: The first logical device of a system (even if the entire physical unit is
configured as one logical device) is known as the System Disk, or DSK0:.
