Changing Extensions
You can perform several operations through the Modify Extensions dialog
box (
Table 11
). This section describes several examples.
Example: If you select Change Extension from the Operation list, the
system replaces the selected extension with the number you type in the
text box.
Example: If you select Strip Leading Digits from the Operation list, and
type the number 2 in the text box, the system strips (removes) two digits
from the beginning of the extension.
Example: If you select extensions 1000 through 1009 and select Strip
Trailing Digits from the Operation list, the system does not make any
change, because the result is a series of identical numbers (all 100).
