Author's Note:
This file is the first of two files dealing with PRIMOS and its operations.
The next file will be in circulation soon so be sure to check it out at any
good BBS.

This file is written in a form to teach beginners as well as experienced
Primos users about the system. It is written primarily for beginners however.
PRIMOS, contrary to popular belief can be a very powerful system if used
correctly.  I have  outlined some  VERY BASIC  commands and  their use in this
file along with some extra commands, not so BASIC.

Logging On To A PRIMOS:
A PRIMOS system is best recognized by its unusual prompts. These are: 'OK',
and 'ER!'.  Once connected, these are not the prompts you get.	The System
should identify itself with a login such as:

Primenet V2.3
Primecom Network

The  system then  expects some	input from  you,preferably:  LOGIN.  You will
then be asked to enter	your user  identification and  password as  a security
measure.  The login onto a PRIMOS is as follows:

Primenet V 2.3 (system)
LOGIN<CR>      (you)
User id?       (system)
AA1234	 (you)
Password?      (system)
KILLME	 (you)
OK,	    (system)

Preceding the OK, will be the systems opening message.	Note that if you fail
to type login once connected, most other commands are ignored and the system
responds with:

Please Login

Logging Off Of A PRIMOS:
If at any time you get bored with Primos, just type 'LOGOFF' to leave the
system.	Some systems have a TIMEOUT feature implemented meaning that if you
fail to type anything for the specified amount of time the system will
automatically log you out, telling you something like:

Maximum Inactive Time Limit Exceeded

System Prompts:
As stated previously, the prompts 'ER!' and 'OK,' are used on Primos. The
'OK,' denotes that last command was executed properly and it is now waiting
for your next command. The 'ER!' prompt denotes that you made an error in
typing	your last  command.  This  prompt is  usually  preceded	by  an	error

Special Characters:
Some terminals have certain characteristics that are built in to the terminal.

Deletes the last character typed.

Other Special Characters:
RETURN:	The return key signals PRIMOS that you have completed typing a
	 command and that you are ready for PRIMOS to process the command.

BREAK/CONTROL-P:  Stops whatever is currently being processed in memory and
		  will return PRIMOS to your control.  To restart a process,
		  START (abbreviated with S).

CONTROL-S:  Stops the scrolling of the output on your terminal for viewing.

CONTROL-Q:  Resumes the output scrolling on your terminal for inspection.

SEMICOLON ';':	The logical end of line character.  The semicolon is used to
		enter more than one command on one line.

Getting Help:
You can get on-line information about the available PRIMOS commands by using
the 'HELP' command.  The HELP system is keyword driven.	That is, all
information is stored under keywords that indicate the content of the help
files.	This is similar to VAX.	Entering the single command 'HELP' will enter
the HELP sub-system and will display an informative page of text.  The next
page displayed will provide you with a list of topics and their keywords.
These topics include such items as PRIME, RAP, MAIL, and DOC.  If you entered
the MAIL keyword, you would be given information concerning the mail sub-
system available to users on P simply enter PRIME to obtain information on all
PRIMOS commands.  You could then enter COPY to obtain information on that
specific topic.

Files And Directories:
The name of a file or sub-directory may have up to 32 characters.  The
filename may contain any of the following characters, with the only
restriction being that the first character of the filename may not be a digit.
Please note that BLANK spaces are NOT allowed ANYWHERE:

A-Z .....alphabet
0-9 .....numeric digits
&   .....ampersand
#   .....pound sign
$   .....dollar sign
-   .....dash/minus sign
*   .....asterisk/star
.   .....period/dot
/   .....slash/divide sign

Naming Conventions:
There are very few restrictions on the name that you may give a file.
However, you should note that many of the compilers (language processors) and
commands on the PRIME will make certain assumptions if you follow certain
guidelines. File name suffixes help to identify the file contents with regard
to the language the source code was written in and the contents of the file.
For instance, if you wrote a PL/1 program and named the file containing the
source code 'PROG1.PL1' (SEGmented loader) would take the binary file, link
all the binary libraries that you specify and produce a file named
'PROG1.SEG', which would contain the binary code necessary to execute the
program.  Some common filename suffixes are:  F77, PAS, COBOL, PL1G, BASIC,
FTN, CC, SPIT (source  files).	These all  denote  separate languages  and get
into more advanced programming on PRIMOS.  (e.g. FTN=Fortran).

BIN=the binary code produced by the compiler
LIST=the program listing produced by the compiler
SEG=the linked binary code produced by SEG

Some files which do not use standard suffixes may instead use the filename
prefixes to identify the contents of the file.	Some common filename prefixes

B  Binary code produced by the compiler
L  source program Listing
C  Command files
$  Temporary work files (e.g. T$0000)
#  Seg files

Commands For File Handling:
PRIMOS has several commands to control and access files and file contents.
These commands can be used to list the contents of files and directories, and
to copy, add, delete, edit, and print the contents of files.  The capitalized
letters of each are deleted.  A LIST must be enclosed in parenthesis.

Close arg	....Closes the file specified by 'arg'.  'Arg' could also be
		 a list of PRIMOS file unit numbers, or the word 'ALL' which
		 closes all open files and units.

LIMITS		....Displays information about the login account, including
		 information about resources allocated and used, grantor, and
		 expiration date.

Edit Access	....Edits the Access rights for the named directories and

CName arg1 arg2	....Changes the Name of 'arg1' to 'arg2'.  The arguments can
		 be files or directories.

LD		....The List Directory command has several arguments that
		 allow for controlled listing format and selection of entries.

Attach arg	....allows you to Attach to the directory 'arg' with the
		 access rights specified in the directory Access Control List.

DOWN <arg>	....allows you to go 'DOWN into' a sub-ufd (directory).  You
		 can specify which one of several sub-ufds to descend into
		 with the optional 'arg'.

UP <arg>	 ....allows you to go 'UP into' a higher ufd (directory).  You
		 can specify which one of several to climb into with the
		 optional 'arg'.

WHERE		....Displays what the current directory attach point is and
		 your access rights.

CREATE arg	....CREATES a new sub-directory as specified by 'arg'.

COPY arg1 arg2	....COPIES the file or directory specified by 'arg1' into a
		 file by the same name specified by 'arg2'.  Both 'arg1' and
		 'arg2' can be filename with the SPOOL command, whose format

SPOOL filename -AT destination
		 where filename is the name of the file you want printed, and
		 destination is the name of the printer where you want the
		 file printed.	For example if you want the file 'HACK.FTN'
		 printed at the destination 'LIB' type:


PRIMOS then gives you some information telling you that the file named was
SPOOLed and the length of the file in PRIMOS records. To see the entries in
the SPOOL queue, type:


PRIMOS then lists out all the files waiting to be printed on the printers on
your login system. Also included in this information will be the filename of
the files waiting to print, the login account name of the user who SPOOLed the
file, the time that the file was SPOOLed, the size of the file in PRIMOS
records, and the printer name where the file is to print.

Changing The Password Of An Account:
If you wish to change the password to your newly acquired account you must use
the 'CPW' command (Change PassWord).  To do this enter the current password on
the command line followed by RETURN.  PRIMOS will then prompt you for your
desired NEW password and then ask you to confirm your NEW password.  To change
your password of 'JOE' to 'SCHMOE' then type:

OK,		(system)
CPW JOE		(you)
New Password?	(system)

You can save a copy of your terminal session by using the COMO (COMmand
Output) command.  When you type:

COMO filename

Everything which is typed or displayed on your terminal is saved (recorded)
into the filename  on the command line (filename).  If a file by the same name
exists, then that file will be REPLACED with NO WARNING GIVEN!	When you have
finished doing whatever it was you wanted a hardcopy of, you type:


which will stop recording your session and will close the COMO file. You can
now print the COMO file using the SPOOL command as stated earlier.

This  concludes	this  first  file on PRIMOS.  Please  remember this  file  is
written primarily for beginners, and some of  the text may have seemed BORING!
However, this filewaswrittenin	a verbose fashion to FULLYINTRODUCEPRIMOS
to beginners.  Part II will deal with more the several languages on PRIMOS and
some other commands.
