1. To improve the utility of the Batch Query Language (BQL) Program
AID has implemented the BQLT Program, a modified version of BQL. BQLT has
been specifically designed to be run from remote terminals rather than from
the computer room. Like BQL, BQLT will retrieve data from the Installa-
tions Data File and from existing private files. AID hopes that the use
of BQLT will reduce the large volume of requests submitted to the AID Opera-
tions Branch for BQL runs and thus give users much faster service.
2. Instructions for using the new program have been included in the
attachment. This memorandum and the instructions will also be issued as
soon as possible to all those who have received user manuals for BQL and
the PIRL Query Language. If you need additional copies of the memorandum
or of the user manuals, please contract Chief of the 25X1
Systems Integration Staff, AID on extensionj _j 25X1
3. We would be happy to brief those in your organization who will be
using BQLT. These would include all personnel who have had training and/or
experience in using either BQL or PIRL. If you would like to be briefed on
the new program, please make arrangements through your ADP coordinator.
We request that he contact Chief of the Information 25X1
Systems Branch, AID/PSG on extension 25X1
4. Please notify all BQL users in your organization to begin using
the BQLT Program as soon as they receive the necessary documentation. We
also request that, during the four working days following the. delivery of
photography to NPIC, BQLT be used for only those queries having
the highest priority.

CHAPTER VIII. THE BQLT PROGRAM
The BQLT Program, a modified version of BQL, has been designed to be
run from on-line remote terminals rather than from the computer room. Like
BQL, BQLT will also retrieve data from the Installations Data File and from
existing private files.
Queries Based on
the IHEAD Sector
When a query specifies that target records be selected from the IDF
solely on the basis of data in the IHEAD sector, no more than 1,000 records
will be selected. If more than 1,000 records must be selected to answer
the query, this message will be sent to the device that transmitted the
query:
OUTPUT TOO LARGE FOR REMOTE DEVICE-RECONSTRUCT QUERY
OR SUBMIT REQUEST THRU PAS, OPB.
For example, a query specifying that all records on USSR targets be
selected from the IDF would exceed this limitation. When constructing
queries about targets located in areas as large as China or the USSR, try
to limit the number of records to be selected by including WHEN, OR, AND,
or USE statements in your query, or by specifying that records be selected
on the basis of their location [WITHIN and EXCEPT statements]. For example,
this query would limit the selection of target records to those which are

25X1
Printing Limitations
If you want the answer to your query printed by a DCT 2000 or a high-
speed printer in the computer room, the number of printed lines will be
limited to 3,500. For example, this limitation would be exceeded if you
were to submit a query that requires the selection of 500 target records
and specifies a report format table that prints 8 lines of data per target
record. In this case, the maximum number of lines to be printed would be
I+,000 [8 X 500].
If you specify that your answer is to be printed by an ASR or KSR
Teletype or by a Kleinschmidt printer, the number of lines to be printed
will be limited to 100.
Whenever these printing limitations are exceeded, an appropriate
message will be sent to the on-line device that transmitted the query. No
output or partial output will be printed.
Queries Based on the IHEAD
and on Other Sectors
If a query specifies that target records be selected on the basis
of data in the IHEAD sector and other sectors in the IDF, no more than 100
records will be selected. If more than 100 records must be selected to
answer such a query, this message will be sent to the device that trans-
mitted the query:
NON-HEADER TARGETS RETRIEVED EXCEEDED REMOTE LIMIT
OF 100
For example, the answer to this query would require the selection of over

The program would terminate, and the message given on the preceding page
would be printed by the teletypewriter associated with the on-line device
being used.
If you want more than 100 records to be selected, submit your request
for a program run to the Operations Branch, AID.

Only these mnemonics for report format tables may be specified in a
BQLT query. [See also CHAPTERS I and II.]

If you need another type of format, a new table can be generated by
submitting a written request for this service to the Chief, Information
Systems Branch, AID/PSG or to your ADP coordinator.
When printed, sectors are preceded by two lines of header data.

TRANSMITTING
BQLT QUERIES
For Release 21 V1' ~CI.RC l
0980001007
BQLT queries can be transmitted to the computer via on-line teletype-
writers or via a DCT 2000. The procedures for transmitting queries are
identical to those described in CHAPTER VI with one exception: specify
BQLT rather than BQL when calling the program on a teletypewriter; or
punch BQLT in your program header card if a DCT 2000 is to be used.
