SUBJECT: Information
Attached are copies of three separate unrelated memoranda and a one page extract
from the EDP Weekly. These are sent just as info:cmation pieces, on the change that
you might have a couple of minutes to read them aid because I thought that you would
find them of interest.
The first one gives a brief description of tae various IIS qVioft programs that
I felt would be of interest to you before the update IIS briefing on 9 April. The
next two note improvements in existing programs, sent just to let you know that we are
continually updating and improving on-going progr ins. The fourth item, from the EDP
Weekly, notes a new Data System and indicat-~s that this is a "first" and the
only system that can per orm the three noted tasks concurrently. The point to note
here is that NPIC, on its, 4+94+ computer has been executing this type of operation for
some time now.

DISCUSSION OF IIS PROGRAM FUNCTIONS AND CORE
MI v1ORY REQUIREMENTS
1. The IIS system consists of the follow_ng functional program
packages that are loaded into the 494 in a variety of mixes dependent
upon a given set of NPIC activities:
a. The Data Entry Program (DEN) allows the photo inter-
preter or his representative to enter tibm_ target oriented
data for use in NPIC immediate reports into an "on-line".
reports file. This program requires approximately 9,000
words of memory and is a remote batch type; i.e., the pro-
gram is loaded via a remote device but its I/O is handled
by the operating system as "batch" messages. The program
is non-interactive but can be core resident for long or
short periods of time depending upon the actual function
performed.
b. The Verify Edit and Approval Program (VFA) allows the
mission editors/coordinators to use a CRT to review and
change information entered via "DEN" above, verifying,
editing and approving it for subsequent publication and
data base update. This program requires approximately
7,000 words of memory and is a remote conversational
type; i.e., a "copy" of the program resides in memory for
each CRT "conversing" with the computer.
c. The Extended File Control Subprogram (EFC) per-
forms all accesses to the drum based IIS J'iles, preserving
the file integrity as well as simplifying file I/O for
other IIS application programs. This routine requires
approximately 3,000 words of memory and is a non-resident
re-entrant type of routine; i.e., core-resident in one
copy when needed, yet shared by all IIS programs. It can
be considered a subroutine common to all programs, yet
using only that core required for one program.

d. The Automated Update Program (AIJD) accepts "approved"
target data (after VEA process) and use:; it to update appro-
priate target in the IDF. This program requires approximately
4,000 words of memory and is scheduled automatically by "EFC"
when there is data base update action to perform.
e. The On-Line Update Program (OUD allows the Data Base
coordinators to recall data from the file on to ?a CIZI'; alter
the data and return it to the data base (via MUD). This pro-
gram requires approximately 6,000 words of memory and is a
remote conversational type.
f. The Batch Query Language Program (BQL) allows IIS file
users to query the files in a manner that requires passing
large portions of the data base, thus requiring processing
times prohibitive to the "on-line" language. This program
requires approximately 18,500 words of memory and is a
remote batch or operator-initiated batch program. Typically,
this program (as well as RPG below) will be limited to one
or two copies in memory during prime time due to size, core
residency time, and volume of I/O activity.
g. The Report Generation Program (I"PG) provides the
generalized capability for "hard copy" formatting of IIS
outputs. This program requires approximately 22,000 words
of memory and is a remote batch type. lhis program, typically,
is called automatically by BQL to format the data acquired
from a selection process. Subsets of this program exist
within the OUD, VEA, and PIRL programs.
h. The PI Retrieval Language Program (PIRL) allows
ITS file users to query the files using concise statements
resulting in limited amounts of highly useful data con-
sisting of specific pieces of file information. These
data are usually displayed on a device with limited
display area. This program requires approximately 10,000
words of memory and is either remote conversational or
remote batch types.
i. The Presentation Language Progran (PLP) provides
the capability to define new or altered report formats
for use by the RPG program. This progran requires
approximately 10,000 words of memory and is a remote
batch type.

(1) 10 VEA programs 70K words
(2) Other IIS programs 77K words*
j. The Periodic Update Program (PUI1) manages the mass
storage for the IIS files. The program redistributes the
data stored in file overflow/add areas into a compact and
efficient arrangement. The program alsc, purges outdated
information from the files. 'thiis progrE.m requires 32,000
words of memory and is a batch type.
2. Since the above programs are scheduled for operation in con-
sonance with NPIC's.workload, it would be erroneous to merely add the
individual program core requirements to arrive at the IIS system core
requirements. Typical mixes along with the resulting core require-
nients are shown below.. From these one can appreciate the 80,000 word.

b. "Normal" IIS activity (typical working day with some

*The periodic update program was not considered in the above "Other
Program Combinations" because it will be scheduled after prime shifts,
or after system failure resulting in a partially "destroyed" data base
(IDF).
