8.6.7 Editing Areas in Symbol Tables
As of STEP 7 V5.3, you can now select and edit contiguous areas within a symbol table. This
means that you can copy and/or cut parts of one symbol table and insert them into another symbol
table or delete them as required.
This makes it easier to update symbol tables by quickly transferring data from one symbol table to
another.
Areas that can be selected:
• You can select entire rows as soon as you click in the first column in the row. If you want to
select all the fields, ranging from the "Status" column to the "Comments" column, then these
are also part of the selected row.
• You can select one or more contiguous fields as an overall area. To be able to select this area,
all fields must belong to the "Symbol", "Address", "Data Type" and "Comments" columns. If you
make an invalid selection, the menu commands for editing will not be available.
• The R, O, M, C, CC columns contain the special object properties for the respective symbols
and are only copied if the "Also copy special object properties" check box is selected in the
"Customize" dialog box (menu command Options > Customize).
• The contents of the R, O, M, C, CC columns are copied if these columns are displayed. To
show or hide these columns, select the View > R, O, M, C, CC Columns menu command.
To edit a symbol table, proceed as follows:
1. Select the area that you want to edit in the symbol table by using either of the following
methods:
- Using the mouse, click in the starting cell, and while keeping the left mouse button
depressed, move the mouse over the area that you want to select.
- Using the keyboard, select the area by pressing the shift key and then the cursor (arrow)
keys.
2. The selected area is shown in reverse video. The cell selected first is shown in normal display
and is surrounded by a frame.
3. Edit the area selected as required.
