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 1-4. 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
language 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 a visual 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 a new-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
considering the need for using new-line operations.
• Word delete
Deletes a word from the current cursor position to the end of the word.
1 A null character is a control character that can 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.
© Copyright IBM Corp. 1983, 1990 1-1

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"
represent 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
anywhere 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.
I Hardware Supported
1 Some terminals have their own version of Entry Assist. Refer to your own terminal
I documentation for additional information.
I For a list of terminals that the 3174 provides Entry Assist support for, refer to the
I 3174 Introduction (GA27-3850). The 3174 Introduction does not list this capability;
I however, any 80-column CUT display listed in the Introduction can use the 3174
I version of Entry Assist.
2 A typematic key repeats its function when pressed and held down.
I 3 For converged and enhanced keyboards in "native mode," you must first place the unit in extended-select mode by
pressing the EX SEL key.
1-2 Entry Assist User's Guide

I Keyboards
r I The Entry Assist function is supported on typewriter, APL, and RPQ 8K1038
I keyboard layouts. Entry Assist Is also supported on converged data entry
I keyboards and on RPQ 8K0808, 8K0932, and 8K1158 keyboards. Some keyboard
keytops need to be replaced with new keytops or relabeled with stick-on labels to
identify the unique Entry Assist capabilities. (See Chapter 2, "Getting Started," for
installation instructions.)
I You can purchase an Entry Assist Keytop Replacement Accessory Kit for some
I keyboards. The Accessory Kit contains eight sets of five replacement keytops and
a keytop extractor tool. Ask your IBM Sales Representative for information about
how to order the Accessory Kit.
I Audible Alarm
I The terminal must have an "audible alarm" in order to obtain the audible "end of
I line" signal function.

^ Chapter 2. Getting Started
This chapter explains how to make Entry Assist work on your control unit. It also
explains how to customize your keyboard.
How to Make Entry Assist Work
On a 3174 Control Unit:
You do not need to do anything special to make Entry Assist work. The Entry
Assist function works automatically and requires no control unit customizing.
On a 3274 Control Unit:
You can find the procedure for making the Entry Assist function work on a 3274
Control Unit in the IBM 3270 Information Display System: 3274 Control Unit
Customizing Guide.
How to Customize Your Keyboard
To customize your keyboard for the Entry Assist function, do the following:
1. Apply the stick-on labels (32 sets of six labels, which must be ordered
separately) to the keyboards, or use replacement keytops (which can be
ordered) on some keyboards.
2. Refer to Figure 2-1 on page 2-2, Figure 2-2 on page 2-2, Figure 2-3 on
page 2-3, and Figure 2-4 on page 2-3. Choose the figure that matches the
keyboard you have and look at the bold-outlined blocks to see how to apply the
stick-on labels. Stick-on labels must be ordered separately.
3. Wash each keytop with soap and water and allow it to dry thoroughly before
you apply the labels.
4. Peel each keytop label off the label form with a sharp-pointed knife (or a
similar device); then position the label on the keytop.
5. Press the label down with a fingertip.
If your display has removable keytops, you may be able to order an Accessory Kit,
which contains eight sets of five replacement keytops engraved for use with Entry
Assist, a keytop extractor tool, and Keytop Replacement Instructions. (See
"Keyboards" on page 1-3.)
If you use the RPQ 8K1038, 8K0808, 8K0932, or 8K1158 keyboard with a 3174 control
unit, you need to customize the control unit to support your keyboard. If you use
the RPQ 8K1038, 8K0808, 8K0932, or 8K1158 keyboard with a 3274 control unit, the
RPQ corresponding to that keyboard must be installed. Ask your system
administrator for assistance if necessary.

^ Chapter 3. Using the Entry Assist Capabilities
This chapter lists the Entry Assist capabilities and tells you how to use them.
Turning On Entry Assist
The DOC ON OFF key turns all the Entry Assist functions on and off.i
I When you first turn on the power to a display unit after the control unit (3174) has
I been powered on or restarted, the Entry Assist functions are turned off.
j To turn on the Entry Assist functions, press the DOC ON OFF key. This puts the
display in "document mode" and causes either the DOC or the D-> symbol to be
displayed in the operator information area (column positions 66-68).
If you have Entry Assist on when you turn the power off your display unit, Entry
I Assist is still in effect when power comes back on with Configuration Support B
i Release 2 or later code. Prior to Release 82, the Entry Assist function is always off
whenever a display unit is powered on. Ask your system administrator which
configuration your control unit is using. If the controller is restarted, then you need
, to turn Entry Assist on.
The D-> symbol is displayed when both "document mode" and enhanced
null/space processing mode^ are active. The DOC symbol is displayed when only
I "document mode" is active.
To turn off the Entry Assist functions, press the DOC ON OFF key while in document
mode. This also clears the DOC symbol (or restores the if enhanced
! null/space processing mode is active).
Using the Formatting Controls
This section lists the formatting controls and explains how to use them.
The Change Format Key
To put your display in change format mode:
1. If you have not entered your display into "document mode," do so at this time.
2. Then press the Change Format (CHG FMT) key.
This action places the display in "change format" mode. You can use the keyboard
controls to set and clear margins, tabs, and the audible "end of line" signal only
when the display is in change format mode. If an invalid keystroke is pressed, it
may be necessary to press the reset key before further keystrokes will be
accepted. Use the change format active keys shown in Figures 3-1 through 3-6 on
the following pages.
' When you are working with Converged or Enhanced keyboards In native mode, first place the unit In
extended-select mode.
2 Enhanced null/space processing mode Is available on 3174 Configuration Support B Release 2 and later.
