For Access, scrolls the display horizontally to preceding
data during an edit or browse session.
For Move, Compare, or Archive, scrolls the display horizontally
to preceding data for the following items:
- During a Point-and-Shoot session.
- When browsing online process reports.
- When browsing the contents of an Extract File, Compare
File, or Archive File.
LEFT [ column | Csr | Page | Data | Half | Max | n ]
- column
- The name of the column that is to be scrolled. The
column can be implicitly specified by positioning the cursor at the
column. This operand cannot be entered when browsing an online process
report.
- CSR
- Cursor location determines the scroll. During an
edit or browse session, a Point-and-Shoot session, or a Compare File,
Extract File, or Archive File browse session, the column in which
the cursor is positioned is scrolled to the right-most position. When
used for expanded data, the character on which the cursor is positioned
is scrolled to the right-most position.
- PAGE
- Full page scroll. During an edit or browse session,
a Point-and-Shoot session, or a Compare File, Extract File, or Archive
File browse session, the column preceding the first displayed column
is displayed in the right-most position on the screen. When used for
expanded data, the character preceding the first displayed character
is displayed in the right-most position on the screen.
- DATA
- Full page scroll. During an edit or browse session,
a Point-and-Shoot session, or a Compare File, Extract File, or Archive
File browse session, the column displayed as the first column is displayed
in the right-most position on the screen.
When used
for expanded data display, the first displayed character is displayed
in the right-most position on the screen.
- HALF
- Based on the current display. During an edit or
browse session, a Point-and-Shoot session, or a Compare File, Extract
File, or Archive File browse session, the column in the middle is
scrolled to the right-most position. During expanded data, the character
in the middle of the display is displayed in the right-most position.
- MAX
- During an edit or browse session, a Point-and-Shoot
session, or a Compare File, Extract File, or Archive File browse session,
the first column in the table is to be scrolled to the left-most position
on the screen. When used for expanded data, the first character of
data is scrolled to the left-most position.
- n
- During an edit or browse session, a Point-and-Shoot
session, or a Compare File, Extract File, or Archive File browse session,
a specific number of columns to scroll the display. When used for
expanded data, the value specifies number of characters to scroll
the display.
- The word MORE followed by an arrow pointing in the
appropriate scroll direction is displayed on the information line
to indicate that scrolling is possible.
- If the left-most portion is currently displayed,
the scroll request is ignored and a message is displayed.
- The LEFT command does not preserve insert-pending
rows. Therefore, when inserting data into a table with a partitioned
index and all key columns are not displayed on the current screen,
use LEFT to scroll the display to the other key columns so you can
enter the necessary data.
- When using the HALF operand, the middle column is
determined by the number of columns currently displayed. If an uneven
number of columns is displayed then the column in the middle is the
one that has the same number of columns on each side.
- The LOCK command can be used to lock one or more
columns such that they are not scrolled when the display is scrolled
horizontally.
- Use RIGHT to scroll the display to the horizontally
and view succeeding data.
- During an edit or browse session, a Point-and-Shoot
session, or a Compare File, Extract File, or Archive File browse session,
the LEFT command is cursor sensitive. When an operand is not specified,
the scroll is performed based on the cursor location.
Columnar Display
- If an operand is not specified, the column containing
the cursor is scrolled to the right-most position and all data that
precedes the column is presented appropriately.
When
a column name is not specified and the cursor is not positioned on
a column in a window, the lowest-level table is scrolled. The column
after the column displayed in the left-most position is scrolled to
the right-most position and all data that preceded the column now
in the right-most position is presented appropriately.
The fully qualified column name should be specified
when more than one table contains a column of the specified name.
The column can be qualified by the table or view name, the identifier
(Tn or Vn) or the cursor position.
Sidelabels Display
- A logical horizontal scroll is performed such that
the columns are shifted to the preceding position.
- The column operand can only be specified for a column
in the currently displayed table.
Expanded Data Display
- If an operand
is not specified, the character on which the cursor is positioned
in the expand window is scrolled to the right-most position and preceding
data is presented appropriately.
- When using the HALF operand, the middle character
in the current display is scrolled horizontally to succeed all other
data in the display.
- The column operand cannot be specified.
