Question about "tellTarget"

Ok,

My first question is how do you specify the target path using “tellTarget”?

Ex. The target movie clip is on the main timeline but the “tellTarget” script is on another. How would I code this? (or should I just use the standard “gotoAndPlay”?)

Second Question

Is tellTarget really even relevant anymore? It seems to me that with the release of FMX 2004, Macromedia advocates using gotoAndPlay more than tellTarget. Why would you use tellTarget when gotoAndPlay does essentially the same thing (or does it?)?

Thank you,
