20.4.2 Inserting a Contiguous Address Range in a Variable Table
1. Open a variable table.
2. Position the cursor in the row after which you want the range of contiguous addresses to be
inserted.
3. Select the menu command Insert > Range of Variables. The "Insert Range of Variables"
dialog box appears.
4. Enter an address as the start address in the "From Address" field.
5. Enter the number of rows to be inserted in the "Number" field.
6. Select the required display format from the list displayed.
7. Click the "OK" button.
The range of variables is inserted in the variable table.
20.4.3 Inserting Modify Values
Modify Value as Comment
If you want to make the "modify value" of a variable ineffective, use the Variable > Modify Value
as Comment menu command. A comment marker "//" before the value to be modified of a variable
indicates that it is without effect. The command marker "//" can also be inserted in front of the
"modify value" instead of the menu command call. The ineffectiveness of the "modify value" can
be reversed by calling up the Variable > Modify Value as Comment menu command again or by
removing the comment marker.
