Preface
This publication explains the Entry Assist function of the 3174 and 3274 Control
Units. Entry Assist provides conveniences and productivity improvements for
display operators who enter and edit text material. This book teiis you what the
Entry Assist function can do and explains how to use it.
Who Should Read This Book
Anyone using 3270 displays for text-related activity should read this book. This
includes secretaries, administrative personnel, clerical personnel, executives,
managers, planners, engineers, writers, and programmers.
How This Book is Organized
Chapter 1, "Overview," gives you a general description of the Entry Assist
function.
Chapter 2, "Getting Started," tells you how to make Entry Assist work on your
control unit. It also explains how to customize your keyboard.
Chapter 3, "Using the Entry Assist Capabilities," lists the capabilities of Entry
Assist
and tells you how to use them. The Entry Assist functions are divided into
two groups:
•Using the Formatting Controls
•Using the Cursor and Editing Keys.
Chapter 4, "Using Entry Assist with IBM Host Editors and Other Applications,"
explains howto
use Entry Assist with some of the IBM host editor programs. You
can also find other application hints on those pages.
Chapter 5, "Entry Assist Tutorial," contains an Entry Assist tutorial for self-
teaching.
A list of abbreviations used in this publication follows Chapter 5.

Chapter 1. Overview
The Entry Assist function provides display units with new capabilities for limited
local format, entry, and edit control when operating with one of the supported IBM
host editors. These editors are listed under "IBM Host Editor Programs" on
page 5. The Entry Assist function provides conveniences and productivity
improvements for 3270 operators in applications involving the entry and editing of
text material. For example, you might want to use Entry Assist to edit or enter
some of the following material:
• Office correspondence, such as letters, memos, reports, lists, and schedules
• Formal publications, such as books, magazines, and brochures
• Source program material, such as COBOL, FORTRAN, and assembler lan
guage source program statements
• Job control language (JOL) statements
• Other text material normally handled by the listed host editors.
Entry Assist Capabilities
The Entry Assist function provides the following capabilities for the operator:
•Display of an "on-demand scale" line for establishing margins, tab stops, and
an "end of line" signal position
Establishes line format parameters, providing avisual indication of the position
of the parameter on the line. (You can view the scale line only in change
format mode.)
• Screen margins
Automatically confines the body of the input material within the margins.
• Tabbing
Moves the cursor to the next tab stop and replaces unprotected null
characters^ with space characters allowing for rapid entry of tabular material.
• Audible "end of line" signal
Warns you of the need to perform anew-line operation.
• Word wrap (automatic new line)
Provides an automatic new-line operation, automatically moving partially typed
words to the next line. The word wrap facility allows you to type without con
sidering the need for using new-line operations.
• Word delete
Deletes a word from the current cursor position to the end of the word.
• Typematic character delete2
Supplements the nontypematic single-character delete.
l^\
1 A null character Is a control character that may be Inserted Into or removed from a sequence of characters without
affecting the meaning of the sequence: however, the control of equipment or the format may be affected by this
character.
2 A typematic key repeats Its function when pressed and held down.
Chapter 1. Overview 1

Document Mode
Typematic character delete^
Supplements the nontypematic single-character delete.
Typematic error-correcting backspace when in insert mode
Deletes while in insert mode.
On-demand cursor position display
Displays the current cursor position in the operator information area in rr/cc
form. (The letters "rr" represent the row numbers and the letters "cc" repre
sent the column numbers.)
Rapid cursor positioning
Provides rapid cursor positioning, which allows you to:
— Move the cursor to the next or previous word with a single keystroke.
- Move the cursor to the next or previous tab stop with a single keystroke.
Both capabilities are typematic, allowing rapid positioning of the cursor any
where on the screen.
To use the Entry Assist functions, press the Document On/Off (DOC ON OFF) key on
the attached keyboard.^ This action establishes "document mode."
Change Format Mode
To establish change format mode, press the Change Format (CHG FMT) key.
(Press the key again to turn off change format mode.)
When the terminal is in change format mode, you can:
• Check the status of margins, tab stops, and audible "end of line" signal
positions.
• Set margins, tab stops, and audible "end of line" signal.
2 A typematic key repeats Its function when pressed and held down.
