performs a Type Look Ahead as you type, and displays the closest tag or
group name to what you enter. By default, the tag control does not allow
you to enter a name that is not contained in the current
.scf
file.
You can configure each tag control, indicator, or constant to permit entry of
names not contained in the current
.scf
file by right-clicking on the tag
object and selecting Allow undefined tags, as shown in the illustration
below. If a tag name is not in your
.scf
file, you cannot select it.
