3.5 DELETING PROGRAM RECORDS
The process of removing Program Records from the file has been
upgraded to save time and give the program a more professional way of
operating. When you wish to delete a record from the disc you must
firstly "MARK THE PROGRAM FOR DELETION". Doing this removes the
Program Record from all catalogues and reports, but does not
physically delete the record from the disc. This gives the user the
opportunity to change his/her mind and therefore rescue the record if
On a regular basis (say once a week) the user "Compresses" the
database. Doing this will physically remove all Program Records
marked for deletion and consiquently "renumber" all records held on
the database. Compressing the database also attempts to "repair" any
corrupted records (referred to as "tattered" records). The following
paragraphs explain the process of deleting Program Records in more
3.5.1 Marking Program Record(s) for Deletion
In order to remove a Program Record from the database, it must first
be marked for deletion. To do this, select the option "Programs For
Deletion" from the main menu and press <return>. You will be
presented with a secondary menu which provides various methods of
deletion which will now be explained ....
22.214.171.124 Deleting a Single Program
This option is used when you wish to delete just 1 Program Record
from the database. The computer will prompt you for a program
number. Enter the correct program number and press <return>. There
will be a short pause whilst the computer finds the correct record
before proceeding to mark it for deletion. You will then be
returned to the Main Menu.
126.96.36.199 Deleting a Range of Programs
This option is used when it becomes necessary to delete a "chunk" of
Program Records that are grouped together on the database. For
example you might have a database with Program Records numbering
from 1 to 100 and you would like to delete records 50 to Record 57
inclusive. The computer will prompt you to "Enter Start Record
Number" to which you would enter "50" and press <return>. You will
then be asked to "Enter Finish Record Number" to which you would
enter "57" and press <return>. The computer will then mark all
records between these two numbers for deletion before returning you
to the main menu.
188.8.131.52 Deleting Selected Programs
This option is used when you wish to delete a selected number of
records which do not fall into any kind of order. For example if
you wished to delete records 1,5,9,13,4 and 33 then you would select
this option to do this. Upon selection you will be presented with
seven "Record" entries to complete. Just enter each record number
you wish to delete and press <return>. It is not necessary to use
all the 7 Record fields provided. Once you have finished just leave
any remaining Record Fields blank by just pressing <return>. When
you reach the last field the computer will mark all your selected
Records for deletion before returning to the main menu.
184.108.40.206 Deleting All Programs
This option will remove all Program Records resident on the
database. Unlike the other options mentioned, this option will
physically remove the database file from the disc without marking
programs for deletion first. Remember: Using this option will
irrevocably wipe all records on the database. If you select this
option then you will be provided with another menu asking you to
confirm your choice. Once confirmed the computer will wipe the
database. Having done this, SYSTEMS server will "Re-Boot". This is
necessary in order to reset program variables. It is suggested that
you *COMPACT the disc before you embark on creating a new database
3.5.2 Why are Programs Marked for Deletion?
With the exception of "DELETE ALL PROGRAMS", none of the above options
(220.127.116.11 - 18.104.22.168) will actually remove a record from the database.
Instead, a software "marker" is placed on the record which will make
it invisable to normal program operations. The reason for this method
is to keep accidental deletions to a minimum. It is quite possible to
recover a deleted program as will be explained later on.
3.5.3 When are Programs Finally Deleted Completely?
A Program Record which has been marked for deletion can remain
(invisably) on the database for as long as the user wishes. "Marked"
Program Records are actually deleted when the database is compressed
3.6 COMPRESSING THE PROGRAM FILE
This option will "tidy" the Program Record file by performing the
following operations ....
a. Physically remove from the disc all Program Records
marked for deletion.
b. Mend any "tattered" Program Records.
c. Renumber all Program Records.
Firstly, all Program Records that have been marked for deletion on the
database will finally be physically and irrevocably deleted from the
disc. Secondly, all "tattered" records (see later) will either be
recovered (or deleted if recovery is not possible). Finally, all the
Program records on the database will be renumbered. Upon selecting
this option you will be asked to confirm your decision before the
computer performs the task. Once complete SYSTEMS server will perform
a "Re-Boot" in order to reset program variables.
It is recommended that this option be used on an infrequent, but
regular basis. For example, it is recommended that the Program File
be compressed once a week or once a month if used infrequently.
3.7 AMENDING & UPDATING PROGRAM RECORDS
This option will allow any kind of amendment to be made to a Program
Record. It is also possible to recover programs marked for deletion
if desired by using this option. THE RELEVENT PROGRAM NUMBER MUST BE
KNOWN WHEN USING THIS MENU OPTION. To amend a Program Record, just
highlight "Amend/Update Programs" from the Main Menu and press
<return>. The computer will prompt you for a Program Number. Enter a
valid number and press <return>. Once the computer locates the
correct number, the whole Program Record will be displayed and the
cursor will position itself on the first letter of the first field
(the "Program" field). Use the following guidelines to amend a
Program Record ...
1. To Begin Amending, just start typing - The computer will overwrite
the existing data. Do not worry if your new data does not
completely overwrite the old data - the computer will insert spaces
at the end of the text if necessary to keep up presentation.
2. To leave a field unchanged - just press <return>.
3. When you reach the STATUS field - 2 possible options are accepted
by the computer - either 0 (live) or 9 (marked for deletion).
You may amend this field if desired (full explanation below).
Once you have reached the bottom of the screen, you will be asked to
CONFIRM or ABANDON the amendments. Use the left and right arrow keys
to highlight the necessary option and press <return>. (If cursor keys
do not work then use the "1" and "0" keys). The computer will perform
any necessary updating before returning you to the main menu.
3.7.1 The "STATUS" Field
You will probably have noticed that the last field on the screen
when amending programs is marked STATUS. This tells us whether
the Program Record is set at status 0 (live), or status 9
(marked for deletion) ...
a. A STATUS OF 0 means the program is "live" and will therefore
appear on all program catalogues etc. etc.
b. A STATUS OF 9 means the Program Record has been "Marked for
Deletion" by previous use of the "Programs for Deletion"
option. This means the Program Record will not appear on any
catalogues and will be physically removed from the disc file
when the "Compress Program File" option is next used.
3.7.2 Rescuing Program Records Marked for Deletion
As stated earlier, it is possible to rescue a Program Record
previously marked for deletion. This is acheived by amending
the STATUS field (explained above) by means of the
"Amend/Update Programs" option from the Main Menu. To rescue a
Program Record, just amend it's STATUS back to 0 (zero).
3.8 LOADING PROGRAMS DIRECTLY FROM "SYSTEMS server"
The SYSTEMS server acts primarily as a Program Record database.
However the option is also provided to load and run a program stored
on one of the "program discs". As you may recall, when you added
Program Records to the database, you entered the FILENAME, LOADING
METHOD (*RUN, CHAIN etc) and DIRECTORY etc etc. Provided this
information was entered correctly, there should be no problems in
loading any suitable program.
To load a program - Select "Load Program Only" from the Main Menu and
press <return>. The computer will prompt you for a program number.
If the program number is known, enter this and press <return>. If the
program number is not known, just press <return> once, then enter the
program name in full (Case Sensitive) and press <return>.
Provided the correct program is found, the relevent loading details
will be displayed on the screen consiting of the following ...
PROG No <the program number> OPTION <loading method ie. CHAIN>
DISC No <Your own disc ref.> SURFACE <disc drive No. ie. 0 or 1>
NAME <title of program ie. SYSTEMS server VERSION 4>
CLASS <classification of program ie. GAME or UTIL etc.>
TAG <access tag - either granted or prohibited - see later>
3.8.1 If Loading Access is Granted
Provided loading access is granted, you will be given the option to
LOAD or ABANDON the option. Abandoning will return you to the Main
Menu. Using the information provided on the screen, place the correct
disc in the correct drive (you may remove the SYSTEMS server disc if
necessary). Once this is done press <return>. The computer will then
check for the correct filing system (moving to DFS or ADFS if
necessary) before exiting SYSTEMS server and loading your desired
program. The loading method used (ie. LOAD or CHAIN or *TYPE) will be
the one stated in the OPTION field (see above).
3.8.2. If Loading Access is Prohibited
Loading will only be prohibited if the "OPTION" field of your selected
program is set to "MENU ONLY" in which case the computer will print
all the loading infomation as before, but the option to load will not
be given. See the next paragraph for details on the "MENU ONLY"
3.8.3 The "M" Option (Menu Only)
SYSTEMS server could be regarded as two program in one. On the one
hand it provides a comprehensive database to store Program Records.
On the other hand, it provides a usefule "Loading Gateway" so the user
can run a program directly from SYSTEMS server without having to press
<Ctrl> <Break> and entering CHAIN "<prog>" etc. etc. When you add
Program Records to the database, you have to specify the "Loading
Option" from a given table (see section 3.1 and refer to the OPTION
Entering M in the OPTION field causes that Program Record to be set to
"Menu Only" which means the Program Record is only for database
reference purposes only and may not be loaded and run by using the
"Load Program Only" option. Listed below are some of the other
reasons why it might be useful to set a program to "Menu Only" ....
1. The program is not readily available (ie. you have lent it to a
friend or relative etc.)
2. The program is "Non Basic" (ie. AMPLE Music 5000 file) and
therefore loading and running the program in BASIC will only cause
the computer to crash.
3. The program is still being written and therefore is Incomplete.
(however LOADing the program from SYSTEMS server should still work)
These are only suggestions. It is completely up to you what settings
you use for each Program Record. Don't forget, you can always change
any setting by using the "Amend/Update Programs" option from the Main
4.1 USER and PROGRAM ERRORS
The SYSTEMS server has been extensively tested and, if used correctly,
should not cause any problems. The most common errors are encountered
when running programs via the "Load Program Only" option when the
wrong disc is inserted or the Program Record settings are incorrect or
the wrong DFS is used etc. etc. When an error is encountered the
computer will stop the program and report the error. SYSTEMS server
will then re-boot in an attempt to save the database Program Records.
Errors that are reported in CYAN are minor errors are are usually
caused by user mistakes (ie. wrong disc inserted etc.)
Errors that are reported in WHITE are rather more serious. When this
happens you should note down the error and the number it gives you (in
brackets). Note down exactly what you were doing at the time and how
the error came about. Then contact me (Duncan Webster) on the Resolve
Communications Bulletin Board (0582 832653) or at the following
Registered users of the bulletin board operated from the above address
may use the helpline phone number already provided for them. Please
report all errors encountered - it will help future inprovements of
the SYSTEMS server and everyone who spots a genuine error will receive
a free, disc with the corrected program on straight away.
4.2 IDEAS FOR IMPROVEMENTS (have you written any software?)
Please use the above address (or Resolve Communications) as a meduim
to forward any ideas or suggestions for improvements that you feel
ought to be made. If you have written any program (game, utility
etc.) that you would like to see published, then send a copy and all
relevent documentation to the address given above. No matter how good
or bad you think it is, I garauntee it will be made available through
the PD library and various Bulleting Boards throughout the Country.
Thankyou for taking the time to read this manual, I hope the SYSTEMS
server works well for you and I hope you find it useful. Should you
wish to receive all future releases of this and other SYSTEMS
programs, then write to me at the address above and I will register

Useful Hints ....
When accessing or searching for program records, the PROGRAM NUMBER
works much faster than entering a program name as the computer can
directly move the disc pointer to your selected program. Entering the
NAME instead of the program number gives no technical disc ref. so the
computer has to sequentially step through every Program Record thus
making the process much slower.
Pressing "E" <return> at most prompts ie. "PROG No" will abandon the
command option. This is especially useful if you change your mind
about marking a Program Record for deletion.
