Invalid list of groups encountered.
#2061 Compile-time error
Invalid list of groups encountered.
Additional Information
The #IMPLIED group cannot appear with other groups.
or
The #GROUPS designation may appear at most once in a list
of groups, but the current action contains more than one.
Recovery
Compilation continues but no compiled source code file will be saved.
Explanation
The #implied group is always active. Therefore it is redundant to
specify that it should be used along with other groups.
Putting #groups in a list of groups more
than once also adds no more information.
