Hmm. I tested this: on testReference put 8 into someVariable put 5 into someOtherVariable setVariable someVariable -- second param omitted answer "someVariable was 8, and is is now:" && someVariable end testReference on setVariable @incomingVar,@someOtherVariable add 1 to incomingVar end setVariable …and got an error message. But if I make the second parameter in the setVariable function *not* by reference on setVariable @incomingVar,someOtherVariable then the same test works. It appears that if you are passing variables by reference you must supply all the referenced variables, but you can leave out non-referenced variables. I'm using an older version of LC: 2008 MacBook, OSX 10.7.4 (Lion), Rev Studio 5.5.1, build 1487. Don't know about lC 6.x or 7.x. -- Peter Peter M.
