INTRODUCTION
The Purpose of this manual is to provide the user familiarity with the
capabilities of the Systemr/3 euery Facility and define the means by
which a functioning syst.r r"y be created.. Described in detail are
the Facility as a system' the operationar aspects of the Facirity, and
a definition of each of the corunand statenents that may be used to
rrrite a query- The necessary functions to tairor the programs to gen-
erate the system are enunerated. For information on how to modify
the Facirity to execute on a system/3 Model 6, refer to the systems
Guide.
SYSTEM O\ER\IIE[.I
%
The system/3 Query Facility is a tool that alrows the user, progreunner,
and non-progranmer alike to selectivery access disk data files f,or prepar-
ing reports or gatherj-ng statj.strcs. By using the functions provided in
four simple -onruner-nds
and the functions of the systen/3 Disk sort, the user
can rapidly formurate queries to the system and receive responses in the
form of printed output without expending time and effort for writing and
testl-ng prograrns.
System Descriptron
The system,/3 Query Facil.ity is cornprised of trro programs written J-n RpG rr.
rnput to the first proqrarn rs the 'sELEcr'and 'soRT,comnands.
This pro_
gran transrates these statements into control statements that are compatibre
wrth the System,/3 disk sort"
upon processing these contrcl statements, the sort utiJ-ity then produces
ajl output file of the records the user has selected, pJ_acing them in the
defrned sequence- Th-is fire then becomes lnput to the second program of
the facility which processes the d.ata and produces a report according to
tlte defrn:'tions established by the 'pRllrr' and ,@tJlJT, command.s. Frgure 4
presents sa:nples of the control statements; Figure 5 illustrates how a
query night be wrj_tten and the resuLting
report.
The commandr; are designed to give a great deal of functior^ to the user and
dernand rittle concern for rigid formatti.ng. They are written in a manner
that conveys meaning to the writer of a query, making a reguest simpre and
direct, and provides resuLts in a minj_mumof time.
Progranrn.t nq SVsterns
?he prograrnlj rdere written and tested under RpG II (5702_RGI , Velston 5,
l4odrficatrotr r,evel- 0) for the system,/3 Model l0 (disk). rnstructions are
provrded fo:r adaptatj.on to a Systernr/3 Model 6. fn addition to the RpG II
compiler, the tirsk sort program (5702-sMr) is required.
Svstem Conf:Lguration
The object programs require 9216 bytes of nemory. With a normal size core-
resident syr;tem control program (approxinatety lX bytes) a 12x central
processor :-r; required. The programs wilL execute on an other:wise minimr.un
System/3 Mor sort work areas and output areas.
PROGRAMDESCRTPTIONS
-
The Systemr/3 Query Facility j-s comprised of two
RpG rr programs. These two
Programs, in conjunction with the Disk sort programr procss
conrnands which result eue:ry Fac1lity
in a printed report contarnj-ng the information selected
and sequenced by the user's cormrands. A discussion of the indivi-duar pro-
grams follows' (For a discussion of commands and their formats refer to
page 1l).
This progrErm processes the user,s 'sELEcr,
'SELECT' and 'soRT, statements. The
statement j-s optional; the 'SORT, statement
is required. The
order in which the two statements are input to the program is not import-
ant. Frgure 1 illustrates the execution of program ANBOI_.
The OG, and data required. for execut:-on rs:
// LOAD ANB01, Fl
// RLIN
qFr Faq,
(optional)
(2nd card of rSEI.FcI'
statement is optional)
J\Jt(t.
/L
The ocl and data are praced in MFCUT. Brank cards
shourd be praced in
MFcu2 for punching the output cards. No printed output is produced.
The punched output consists of system/3 sort specifications which are
suppried as input to ttre sort phase. (see the section "operations rn-
structions") .
The following limitations are placed on the "sEr,Ec:l,,and "S9RT,,statements:
a. The 'SELECT'
statement may span only two cards.
b- A maximum of lo "sELEcr" relationships may be specified in the
"SELECT" statement.
c' A maximum of l0 data element names may be specified in the ,SoRr'
statement.
rf requirements are such that these linits must be exceeded, this must
be planned for at generation time. Instructj-ons for modification are
included on page 20.

'PRIIIT' statement is
required; the 'cotr.lrr statement is optj.onar. The
order in whj-ch they are input is not important. Figure 3 illustrates the
flow for this progran. The disk input file, which was produced by the
sort phase, is interpreted for printing and tabulation via the 'pRl:NT'

Modification Aids
There are two basic categories of modifications discussed elsewhere in
the docunentation. The first category involves tailoring the prograns to
the hardware configuration (Systern/: Model l0) and specific master file
of the user. This includes modifying for increased printer capacj.ty,
allowing for more information in control statements, and adjusting for
the size of the Data Element Dictionary" These changes are presented in
detail in ttre section on "Installation Instructions", pages 16 to 23 of
this manual.
The second category which :-s a general discussion on how to nodify these
programs to execute on Lhe Systen,/3 Model 6 is contained in the Systems
Guide.

(a query') informs This set of,conunands
the system which specific records to serect, the sequence
in which to output the records, the data to print on the output report, and
the nruneri-c data fier-ds for which
totar-s are to be accumulated. A query
can be cromprised of four statement
types" Their detailed descriptions and
formats are found in the following pages.
rsoRl I
Control Statement
The 'SOFJT statement is required for any query. This conunand def:-nes how
the records are to be sequenced by specitying-the
data element natnes to use
for sequencing' The first data element name has the most significance
sorting; in
the last is least significant" All sequencing is assumed to be
ascendj'ng; descending sequence for specific
data elements can be specified
(see below) . The normal System,/S col:-aeing sequence
i-s used, whi-ch, in
generar, treats bLanks and speciar characters as r-ovrest valr:es, forr_owed
by alphabetic characters (A to z) , then by numerics (0
to g). For more
detaiL, refer to the Disk Sort ManuaL (SC2l_7522)
.
The format is as follows:
SORT der r de, , de, , d"r.,
where d:r, a data erement name. The characters 'soFT'must
1" s.tart in
corumn r of the card and be followed by one or more blanks. Data eLement
names must be separated by comnas, and any number of branks (0 up) may
follow a conma- The Program is written to allow a maximum of l0 data
el-erent names in ttre 'soRT'i statement. As previousry rentioned, a d,ata
element can be specified as a descending sort contror fierd. This is
accomplished by sinply folrowing the data erement name in the ,soRT,
conunand by ttre characters '-D'.
The fol-lowing are examples of 'SORT' statements:
SORT STATE, CITY, NAlttE
SORT \ENDOR, TIEM
SORT SALES-D
SOFT AGE, IQ-D, GRADE
'SELECTT
Control Statement
The 'SEIIEO| statement gives the user the abilitl/ ro extract records from
hj-s data file using the por^rer of Boolean logic. Records that meet tl:e
criteria specified in the 'sELEcrt statement appear j-n the outprrr report;
11
aLl- others are ignored" This Eives the user the abil.ity to retrie.ye cate-
gories of data from hi-s fil-es (such as all the customers iu New yo:rk or
all back-ordered itens). Jt is aLso possible for the user to elqll:re his
files seek.inq unique relatiorrships and correlations. This techniq,ug rn.t
be used to discover trends i:r olher patterns not readily provided ioy other
programnrng technrques .
The 'SEJ'ECT' statement is comprised of a series of Boolean relationships
that are rinked together tiy the 'AND' or 'oR' logical operators. The
Boolean relationships are sirnple comparisons between two data elements or
between e riata eLement and a constant. The rel-ationship is enclosed in
parentheses. T'o forrn the rellationsh.ip, ihe two data element nannes (or
data eLement and const-ant.) 11tr Eiep;irated by the comparative operators EQ
(equal ), NE (not equal), j.,T {l"ess than), GT (greater than), LE (less t}ran
or equal) , @ (greater than or eciual). The first name rn the relatbionship
must be a data element name; the secorrd may L:e a constant or a data ele-
nent. nane (tf it is not forurd in the Data Element Dictionary by the pro-
grarn' it is assr-uned to be a constant.) . Alphabetic constants may brg from
I to 20 characters in length. Numerj-c constants can be from I to .[5 digits;
in addition' a minus si-gn may preceerl the nuneric constant and a drrcimal
poj"nt may be inserted. sone exanples of these relationsliips are:
{AGE 61 20) d. e. - cons'Eant
(AG Ct 20.0) equj-valent to above d.e. - constant
(NAIG EQ JONES) d.e. - cons:tant
(NAI4E NE ) d. e. - cons'tant (blanks)
(NAME GT AAAAA) d.e. - cons'b,Eu1t
(reup LT -10) d. e. - cons'tant
(oNHAliD' @ ONOFDR) d.e. - d.e.
To construct a 'SELESI' statement, the Boolean relationships are l:Lnked
together by the linkage operators 'AND' or 'OR' to define the tota.L criteria
by which tc, extract the r e c o r d s . The format is as folloqrsr
SELECT (Relr) ANp,/oR (ReI?) AND/OR (Rel )
n
The characters 'SELECT'must begin in card (two cards
colurnn I of the first
are permitt.ed) followed by one or more blanks. The 'AND' and 'OR' opera-
tors may be preceeded or foll-owed by one or more blanks. If 2 cards are
used for tbLe statement, the data in the first card must end with a right
parenthesis, (')') and the second card must begin with the operator 'Al.lD'
or noR' in colunn '1t.
