Accounts are sometimes called disk accounts because each account is specific to a particular device—
usually a disk. For example, you may have the account [63,1] on both DSK0: and DSK1:. Though these
accounts have the same account number, since they are on different devices they are different accounts,
and contain different files.
You can also assign a password to each account on each disk. This provides limited security by making it
more difficult for someone who doesn’t know the password to log into the account. Please see the AMOS
User’s Guide for more information on disk accounts, passwords, and other AMOS security measures.
You can list the accounts on any device using the PPN command. Type PPN and the name of the device
you want the list for, and press
ENTER
. For example, to see all the accounts on DSK0:, type:
PPN DSK0:
ENTER
There is more information on the PPN command in the AMOS System Commands Reference Manual.
You can also add new accounts by using SYSACT, as described later in this chapter.
File Names
AMOS file names are shorter than those you may know from other operating systems, such as Windows.
An AMOS file name contains up to six characters, a period, and an extension of up to three characters
(the extension can be blank). File names can contain only letters and numbers, except for the period
before the extension. These are legal AMOS file names: AMOS32.INI, HEADER.TXT, PAY.BAS.
The extension normally identifies the type of file. In the previous paragraph, for example, TXT indicates
a text file and BAS indicates a BASIC program file.
You can see a list of the files in any account by using the DIR (short for directory) command. To see a
list of the files in the account you are currently in, type:
DIR/W
ENTER
For more information on DIR, please see the AMOS System Commands Reference Manual.
File Specifications
A complete file specification includes all the parts we’ve discussed: device, account and file name. By
convention, the device name comes first, followed by the file name, then the account. This is the format:
DEVn:filena.ext[#,#]
DEVn: is the device name, filena.ext is the name of the file, and [#,#] is the account number. With some
AMOS commands, the account number can come before the file name, but the device name always
comes first.
If your computer is attached to other AMOS computers via a network, you can refer to a file on
another computer by adding the CPU ID of the other computer to the beginning of the file
specification.
