actually the short way returns an error

[Ops]

Christopher,

Actually, Malte also responded with the corrected "shorter" version and 
he is correct.  My bad, in my zeal to explain the difference between a 
quoted literal string and the actual object name, I overlooked the 
fundamental syntax of what I sent!!  SORRY!!

In the example I sent, there is a precedence problem.  To make the 
evaluation sequence clear for the Rev engine, enclose "pointer" & i in 
double quotes.  This tells the Rev engine to "do this first".  So, (as 
Malte already stated) the corrected version is:

repeat with i = 1 to 3
      set the angle of graphic ("pointer" & i) to rotAngle
end repeat

The precedence is generally pretty intuitive as to how you the human 
(programmer) thinks...but...in some cases one must override the 
precedence rules by surrounding certain constructs inside ()'s in order 
to indicate to the engine that these phrases (the one's in ()'s) should 
be done FIRST.

Again, sorry, and hope this is *all* clear now :)

Opie

P.S. Don't know what kind of graphic that pointer1 is...but...in my 
test, although it compiled correctly with the above...*my* pointer1 
didn't seem to rotate...don't know why, but I also tried it with an 
image and it worked perfectly...I usually manipulate a graphic by 
changing it's points property...

Cheers!!
