4-BThis Library Memo announces the release and availability of Updating Package B to “SPERRY UNIVAC Operating System/3 (0S13)Basic Data Management User Guide”, UP-8068 Rev. 4.
This update for the 8.0 release indicates the availability of a new conversion routine for basic data management. This routine is the OS/3 Sequential DTF Mode to CDI Mode Converter (DTFCDI3O1). This converter processes a basic data management BAL source program module and produces a consolidated data management source module that, with minimal modification, can be used in the consolidated data management environment.
All other changes are corrections or expanded descriptions applicable to features present in basic data management prior ot the 8.0 release.

UP-8068 Rev. 4 SPERRY UNIVAC OS/3 Preface 1 BASIC DATA MANAGEMENT
Preface
This manual is one of a series designed to instruct and guide the programmer in the use of the SPERRY UNIVAC Operating System/3 (OS/3). This manual specifically describes OS/3 basic data management and its effective use. Its intended audience is the applications programmer with a basic knowledge of data processing, but with limited programming experience, as well as the seasoned applications programmer.
Two other manuals are available that cover OS/3 basic data management; one is an introductory manual and the other is a programmer reference manual (PRM). The introductory manual briefly describes OS/3 basic data management and its facilities. The PRM provides the characteristics of OS/3 basic data management in skeletal form and is intended as a quick-reference document for the programmer experienced in the use of OS/3 basic data management.
For systems with interactive facilities, an additional series of manuals is provided to instruct and guide the programmer in the use of OS/3 consolidated data management.
These are:
s Introduction to consolidated data management, UP-8824
• Consolidated data management concepts and facilities, UP-8825
• Consolidated data management macro language user guide/programmer reference, UP-8826
In general, any further references to the term data management in this user guide imply basic data management.
This user guide is divided into the following parts:
• PART 1. OS/3 DATA MANAGEMENT
Introduces OS/3 data management in terms of what it is and how it is used;
introduces and briefly describes consolidated data management; describes the data management/user interface and the relation of data management to other OS/3 software.
UP-8068 Rev. 4 SPERRY UNIVAC OS/3 Preface
BASIC DATA MANAGEMENT Update A
• PART 2. CARD, DISKETTE, and PRINTER FILES
Describes file and format conventions and the function and operation of OS/3 data management in relation to punched card, diskette, and printer files.
• PART 3. MAGNETIC TAPE FILES
Describes file and format conventions and the function and operation of OS/3 data management in relation to magnetic tape files.
• PART 4. DISK FILES
Describes file and format conventions and function and operation of OS/3 data management as related to disk files. Describes the indexed sequential access method (ISAM) both with and without an index structure, the sequential access method (SAM), the direct access method (DAM), the indexed random access method (IRAM), the multiple indexed random access method (MIRAM), and the nonindexed access
method. Also includes information on disk space management.
• PART 5. PAPER TAPE FILES
Describes record, character, and file conventions and the functions of OS/3 data management for perforated paper tape files.
• PART 6. APPENDIXES
Provide selected functional characteristics of peripheral devices relevant to data management use; explain the OS/3 data management procedures for error and exception handling; compare the EBCDIC/ASCII/Hollerith codes and other card codes used in OS/3; describe the systems standard labels for magnetic tape and disk files;
and describe the consolidated data management migration considerations.
Statement Conventions
The conventions used to delineate the data management macroinstructions are:
• Positional parameters must be written in the order specified in the operand field and must be separated by commas. When a positional parameter is omitted, the comma must be retained to indicate the omission, except for the case of omitted trailing para meters.
Examples:
Assume that CNTRL is a data management macroinstruction with three optional positional parameters: A, B, and C.
TAG1 CNTRL A TAG2 CNTRL A,B TAG3 CNTRL A,B,C TAG4 CNTRL A,,C
UP-8068 Rev 4 SPERRY UNIVAC OS/3 Preface 3 BASIC DATA MANAGEMENT
A keyword parameter consists of a word oracode immediately followed by an equal sign, which is1 in turn, followed by a :specification. Keyword parameters can be written in* any order in the operand field. Commas are required only to separate parameters; however, a comma must neither be coded in column 16 of a continuation line nor follow the last keyword of a string.
Example:
Assume that the data management DTF macro for a card file (called CARDIN) has three keyword parameters: IOAREA1, BLKSIZE, and WORKA.
CARDlN DTFCD IOAREA1=AREA1,BLKSIZE=80;WORKA=YES
• Capital letters, commas, equal signs, and parentheses must be coded exactly as shown. The exceptions are those acronyms that are part of geheric terms representing information to be supplied by the user and the commas preceding keyboard parameters of declarative macroinstructions. (These commas serve to remind the user that keyboard parameters coded in a string ust be separated by commas.)
Examples:
Ft ELDS=([AD DR][,A2TD][,FR EQJ) REOC=(MERGE,label,reel,to) CMceNUMBCHAR=n
X aa (NOV)
m Lowercase letters and words are generic terms representing information that must be supplied bythe user. Such lowercase terms may contain hyphens and acronyms (for readability).
Examples:
name sta rt- addr
number-of-bytes pa ram-i
CCB-name
• Information contained within braces represents mandatory entries of which one must be chosen.
Examples:
ffilename
UP8O68 Rev. 4 SPERRY UNIVAC OS/3 BASIC DATA MANAGEMENT
Preface A
I Information contained within brackets represents optional entries that (depending upon program requirements) are Included or omitted Braces within brackets signify that one of the specified entries mustbe chosen if that parameter isto be included.
Examples:
[I NPUT=NO]
[OUTPUT=NO]
I
JworknameL’o
• An optional parameter which has a list of optional entries may have a default specification which is supplied by the operating system when the parameter is not specified by the user. Although the default may be specified by thern user with no adverse effect, it is considered inefficient to do so. For each reference, when a default specification occurs in the format delineation it is printed on a shaded background If by parameter omission, the operating system performs some complex. processing other than parameter insertion it is explained under an if-omitted heading in the parameter description.
Examples:
F,M ERG
L
iNCF
JASCIIL
iEBDUDH• An ellipsis (series of three periods) indicates the omission entries.
Example:
of a variable number of
param-1 param-n
• Commas are required when positional parameters are omitted, parameter specified.
Example:
except after the last
positional parameter 1, positional parameter 2,, positional parameter 4
