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 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 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.
