Well that might be it...parameter copying (Cloning) definitely wasn't around until V3.xx of the Hog 2 software.
If you're talking about Hog 3 copying ("copy to") functionality, that was never implemented in Hog 2...in Hog 2, you have to Copy From (Pig+Copy)...for example, in Hog 3, if you wanted to copy parameters FROM Fixture 1 TO Fixture 2, the syntax is "Fixture 1 Copy Fixture 2 Enter". To do the same thing on the Hog 2, (as Tom indicated) the syntax is reversed: "2 Pig+Copy 1 Enter". In both Hog versions you have to have Fixture 1 parameters "touched" in the programmer for the copying to work.
