IBM 3270 User Guide

Chapter 4. Using Entry Assist with iBM Host Editors and Other
Appiications
The Entry Assist function is easy to enter and exit. If you are an occasional user,
I remember that you need only press the Document Mode key to turn Entry Assist on
I and off.
Selective Use of Entry Assist Functions
You can use the Entry Assist capabilities selectively. Even if you are not working
with one of the IBM host editors, you may still find it useful to operate with
document mode on and use some of the Entry Assist capabilities.
Operating in document mode is similar to operating in non-document mode if the
parameters are set in a certain way. For example, if default margins are set at
columns 1 and 80, word wrap is off, and no tab stops are set, the following
functions are still available:
• Move cursor by word
• Cursor position indicator
• Delete word
• Typematic delete character
• Line ending warning signal
• Backspace delete while in insert mode.
Using Entry Assist with IBM Host Editors
When using a full-screen editor that has a line command field, set the margins to
prevent inadvertent entry of data into the line command field.
• If the line command field is to the left, set the left margin in the first entry
position to the right of the command field.
• If the line command field is to the right, set the right margin just to the left of
the command field. Most of the time, the editor you are using indicates the
data entry area.
1 When document mode is on and tab stops are set, the tab key may cause space
I characters to replace null characters as the cursor moves to a tab stop. (See
I "Enhanced Cursor Tab" on page 3-12.) This action preserves formatting
information in the data stream. Set tab stops only in those situations where the
host program can handle the space characters.
System Productivity Faciiity (SPF)
When using SPF edit functions, set the left margin to correspond to the entry area.
To set the left margin, press the Change Format key and move the cursor to the
beginning of the typing area. The scale line cursor is automatically in the same
column position, and you can immediately set the left margin at this position.
Set the right margin in the right column position.
