Performance Equations C
Do not use these Point Source characters or change the default Point
Source characters for these applications.
If a Point Source character is not explicitly defined when creating a PI
point, the point is assigned a default Point Source character of Lab (PI 3).
Therefore, do not use Lab as a Point Source character for an interface to
avoid confusion.
Do not use a Point Source character that is already associated with another
interface program. However, it is acceptable to use the same Point Source for
multiple instances of an interface.
