IBM 1130 User Manual page 5

this organization is an Installation Activity Schedule,
which highlights all the events leading to a success-
ful installation. This is fully described in Section 05.
This Guide should become a working document in
your organization. Although the experience and
specific needs of each organization vary consider-
ably, all the events apply to some extent in every
installation.
A WORD TO DATA PROCESSING MANAGEMENT
In addition to the comments directed toward top
management, several thoughts apply here.
You are the men in the middle - between top
management and the programmer/analyst. For this
reason the sections checked for your attention are
those concerned with how to do things the "right"
way; how to avoid potential pitfalls; how to get the
most out of your 1130 system; etc.
A WORD TO THE PROGRAMMER/ANALYST
As Figure
01.1
shows, this manual is directed pri-
marily toward you; you should read its entire con-
tents. This is especially true for those of you who
are working in a commercial, or mixed, environ-
ment.
However, the distinction between a commercial,
or mixed, environment and a "pure" scientific
environment is very tenuous. More and more,
users who once considered themselves "pure"
scientific find their applications taking on aspects
of the traditional commercial job - large data files
are developed, input and output formats become
more critical, alphabetic codes and data are en-
countered.
Actually, the subjects checked for the "pure"
scientific reader represent a bare minimum. Any-
one who is or expects to be in a mixed environment
should read the entire manual.
SUMMARY OF THE USERIS GUIDE
The Installation Phase
The following listing of the material in this Guide
reflects the major grouping of installation events
and should provide an indication of the Guide1s com-
prehensive nature. Comments have been added to
each listed item to relate the manner in which that
subject matter may be used.
• Preinstallation Planning - provides a proven
method of scheduling and reviewing installation
activities, specifically tailored to the 1130 user,

and illustrates the points where management review
is most essential.
• Documenting Current Applications - concerns
the control and techniques that can be applied to the
documentation of existing procedures. Distinction
is made between manual operations and those already
mechanized.
• Some Preliminary Questions and Answers
Regarding Data Storage - considers the pros and
cons of using either cards or disk for data storage.
Also considers protecting your data - why and how
it should be protected.
• 1130
Application Design - includes card and
form design, record layouts, and flowcharts. The
elements of application design are made clear
through "live" illustrations, which are used through-
out. This section also aids in the selection of the
right job-oriented programming language and thus
contributes to the effectiveness of the whole installa-
tion effort.
• Program Development - devotes itself to con-
verting designs for 1130 applications into tested,
debugged machine programs. The application dis-
cussed throughout the Guide is provided to serve as
a teaching aid and time saver for the programmer.
Programming hints and aids are also provided.
• Testing Effectively - shows the methods an
installation should use in testing individual programs
and complete systems.
• Program Documentation - shows how a good
set of working documents, which a computer instal-
lation must develop, can be created during the
development phases.
• Conversion - outlines the procedures required
to perform the cutover from your present system to
the 1130.
The Operations Phase
This portion of the Guide contains several sections
of interest to users who have completed the installa-
tion phase:
• 1130 Computing System - contains a compre-
hensive description of the
1130
System and a brief
description of each component.
• 1130
Disk Monitor System - discusses the
1130
Monitor in general and leads into the more
detailed material of the next three sections.
• Job Management - covers those features of
the Monitor that help you manage the job, or unit of
work.
• Disk Management - describes the layout of
disk storage, how you may use it, and how to get
the most out of it.
