The functions of the "JOB BUILDER" remote batch processing subsystem
are described, and instructions are given for using it as a component
of a display system developed by personnel of the System Programming
Laboratory, Institute of Space Research, USSR Academy of Sciences.
Introduction
The "JOB BUILDER" remote batch processing subsystem is designed
for preparing, queuing, implementing, and viewing the results of
user tasks. Tasks are input and results output by means of display
terminals.
The remote batch processing subsystem is part of a display sys-
tem based on BSAN displays. It runs under the control of the
DOS/ES 2.0 operating system.
The user can enter his task in the input queue from the sub-
scriber's terminal and obtain output directly at the subscriber's
terminal from the output queue. However, the user cannot act on
his task once it has been placed in the job queue.
"JOB BUILDER" REMOTE BATCH PROCESSING SUBSYSTEM
I G. Orlov and T. L. Orlova
1. Basic Operating Principles and Capabilities of the Remote	 /4*
Batch Processing Subsystem
The remote batch processing subsystem functionally consists of
two groups of programs:
1) programs operating within the framework of the display system;
2) programs that supplement the DOS/ES operating system.
At the subscriber's console the user formulates his task, enter-
ing data and/or the program text both from the console and from the
display system source module library. The user is accorded the
possibility of editing and scrolling through the input sequence of
lines.	 After finally formulating the text of his task, the user
enters the request "PLACE TASK IN JOB QUEUE." The "BUILDER" sub-
system enters in the source module library the text of the task
input by the user,and places a reference to the task in the job
queue. The task is assigned a number which lights up on the
display screen.
Then the programs running under the display system complete
their work on the given task. A task placed in the job queue will
be implemented in a different section. This section is called the
subordinate section, and usually has a lower priority than the
display system.
* Numbers in the margin indicate pagination in the foreign text.
1
Implementation of the task is initiated in the subordinate sec-
tion by supplementary phases of the "Job Management Program."
Upon completion of any job executed in the subordinate section,
the programs of the remote batch processing subsystem check whether
there are jobs in the job queue. If the job queue is empty, a new
job is entered from the job input device. If the job queue contains
jobs ready for processing, input is accomplished from a section of a
direct-access device. The entire text of the job entered from the
subscriber's console is copied from the display system source module
library onto a section of the direct-access device. Then all entry
of the job is accomplished from the direct-access device.
System printing also is assigned to a section of the direct-
access device.
Programs running under the display system of the Institute of 	 /5
Space Research, USSR Academy of Sciences, perform three basic
functions:
1) shaping of the task (TASK);
2) scrolling of the results of task processing (LIST);
3) determination of the status of the task in the job queue (TEST).
One function can be performed in one run of the remote batch
processing program.
After the remote processing program is called as a component of
the display system of the Institute of Space Research, USSR Academy
of Sciences, the following message is sent to the display console:
LINTER NAME UN BUILDERS REGIME: LIST, TEST, TASK
Depending on the function selected, the user enters one of
three possible replies: LIST, TEST, TASK. If the user does not re-
quire any of the functions offered component of the display system
[sic], he enters the response [sic]
2. Formation of Tasks
Tasks are formed after entry of the function name "TASK." The
user is accorded the opportunity to form a task and place it in the
job queue. There is a set of regimes of the TASK function for making
changes in a sequence of lines that has been entered. The regimes
of the TASK function are defined by special statements. A dis-
tinguishing feature of the statements for this function is the
presence of the symbols "1 10." All lines entered, with the excep-
tion of the regimes of the TASK function, are given numbers. If
the sequence of lines is altered (if lines are eliminated, replaced,
or adOed), the line numbers are corrected. The numbers are set
automatically.
As standard procedure, each line is assigned a number one
larger than that of the last line.
3. Reeimes of the TASK Function
1) DADDi
The regime %%ADD [sic] shows that the next line entered must be in-
serted in the existing sequence after the line numbered i.
2) $ ,11IRE p i shows that the next line entered will replace the line	 lb
numbered [i] in the existing sequence.
3)` OF.Li
The regime r 1 .DEL indicates that the line numbered i must be
eliminated from the existing sequence.
3
W,
4) %%LSTi
	
(format "a")
%%LSTj , X	 (format "b")
%%LST
	
(format "c")
The regime %%LST is used to output to the display one or several
lines of the existing sequence.
Depending on the regime statement format, either line i (format
"a"), lines j through t (format "b"), or all lines (format "c") are
output to the display.
5) %%END
The regime %%END interrupts execution of the TASK function.
The task formulated is not placed in the job queue.
6) 1%RUN
The %%RUN regime completes execution of the TASK function. The
task formulated by the user is placed in the job queue. After this
regime is implemented, the user is given the message:
YOUR TASK IS QUEUED. REMEMBER ITS NUMBER. IT IS iii
[where] iii is the number of the task in the queue.
If the task crnnot be placed in the queue (the queue has overflowed),
the following message is sent:
YOUR 'TASK CANNON' BE QUEUED
4. Viewin., Results of Task Nrocessin
After the user's task is pi-ocessed in the subordinate section,
the results of the job, output for system printing, are buffered in
the direct access volume. The LIST function enables the user to
view all buffered text on the display screen.
4
_ivided into pages 7 alphanumeric printer
lines long. Each line output for system printing is presented on the
display screen either as two lines or as one line. The presentation
format is determined by the user.
The user can view the text beginning at any position. The	 /7
initial position from which text is viewed, and the presentation
format are determined by LIST function regimes.
When the LIST function is called, the following message appears
on the display screen: ENTER TASK NUMBER. The user can enter one of
two replies:
n	 n - 1 to 255 -- the number of the job whose results the
user wants to view.
END	 -- complete job.
If the number of a job that has not yet been executed is en-
tered, the following message appears in the first line on the screen:
BOOK IS NOT FOUND
After the number of an executed task is entered, the following
message appears in the first line:
TASK nnn PAGE 000
Viewing of the listing sections required by the user is accom-
plished by entering control statements of the LIST function. When
this is done, the first line on the screen always contains the
following message:
con'%.r. statement reaction "TASK Pan PAGE jjj
where
5
contr. operator -- the name of the last control statement entered;
reaction	 -- the reaction to the last control statement
entered:
a) spaces indicate that the statement has been
executed;
b) INVALID REGIME--indicates that the control
statement is not recognized or requires for-
bidden operations (e.g., scrolling through a
page with a nonexistent number);
c) END OF TEXT FOUND--the end of the listing
being viewed has been reached.
-- the number of the task whose listing is being
viewed;
-- the number of the page to which the second line
output to the screen belongs (as stated above,
the first line always contains control
information).
5. Control Statements of the LIST Function	 /8
1) Fi	 i = 0 to 57
The statement F changes the format for representing printout on
the screen. If i - 0, one line of printout (121 bytes) is repre-
sented by two lines of display. The first line will contain 64
bytes, the second 57 bytes. It should be kept in mind that in the
DOS/ES system the first byte is the printing control byte and does
not appear in ordinary printout.
If in the control statement F i = 1 + 57, then 64 symbols of
an alphanumeric printer line are presented in a single line of the
screen, beginning with the i-th position. The statement F acts on
all other control statements of the LIST function. If no F state-
ment is entered, the system assumes F is 0.
6
TZ) Ji	 i - 0 to 999
The statement J causes 15 lines to be output to the screen,
beginning with line 0 of the i-th page.
Note. One page contains 7 lines of printout.
3) Pi	 i - -999 to 999
The P statement causes 15 lines to be output to the screen,
beginning with line number m + Fi, where m is the number of the top
line when the P statement is entered. In other words, the P state-
ment makes it possible to move the printout i pages forward (when
i > 0) or i pages back (when i < 0) with respect to the current
printout display on the screen.
Note. If i - 1, the statement may be entered in the form P.
4) Ti	 i - 0 to 999
The T regime makes it possible to output 15 lines to the
screen, beginning with the i-th line.
5) Li	 i = -999 to	 9
The L statement 15 lines to be output to the screen, beginning with
line number i + m, where m is the number of the top line when the
L statement is entered.
In other words, the L statement makes it possible to move the
printout i lines forward (i > 0) or back (i < 0) with respect to the
display present on the screen.
7) Z
	 /9
7
The Z statement makes it possible to output the last page of the
printout to the screen.
8) END
The END statement makes it possible to complete execution of the
LIST function.
9) PRINT i,j	 i,j - 1,999
The PRINT statement makes it possible to output to an alphanumeric
printer a portion of the printout, beginning with the i -th page and
ending with the j-th. If an alphanumeric printer is inaccessible
to the display system, the message NO PRTNTER (printer unavailable)
is output to the screen. if an alphanumeric printer is available
for the display system, the screen is placed in the printer queue.
In any case, the PRINT statement terminates execution of the
LIST function.
6. The TEST Function
The TEST function is used to obtain the status of a task.
The number of the task whose status must be determined is en-
tered in response to the system prompt
ENTER TASK NUMBER
The number is entered in the form
n	 n - I to .155
One of three possible replies is given:
8
f=
YOUR TASK WAS NOT QUEUED 	 -- the task was not placed in the
queue
YOUR TASK IS QUEUED AND 	 -- the task is in the job queue,
NOT PROCESSED
	
but has not been processed
YOUR TASK IS ALREADY PROCESSED
	
-- the ta3k has been processed

Program for Printing Results of Task Processing under Control of
Remote Batch Processing Subsystem
k
I`	 The program for printing the results of task processing under
the control of the remote batch processing subsystem is a program
independent of the display system. Under this program results are
printed in batch mode under the control of the DOS ES system. The
i	 name of the calling phase of the print program is BUILDPRT.
The print-results program has one control statement: PRINT.
The statement format is PRINT I [where] I is the number of the
task whose results are to be output for printing.
Any number of PRINT statements can be processed in a single
run of the print program. If an invalid statement appears in the
print-results program or if the results of the processing of the
task having the required number are not available, an error message
is output for system printing, and the program run continues. The
program stops running when there is an "End of File" status at the
job input device. The results of the program run are culled from
the file bearing the program name LISYSSL 1.
Sample task for running the print-results program.
