naming variables...

[Dennis Brown]

It is not a scripting error if you are following the Reference  
Documentation supplied with Rev:
-----------------------------------------------
How do I create and use a numbered set of variables?

To easily create a set of variables with similar names (such as  
"myVar1", "myVar2",...,"myVar20"), you can use the concatenation  
operator &.

The following example shows how to use a set of variables named  
"myVar1", "myVar2",...,"myVar20":

   repeat with x = 1 to 20
     put empty into ("myVar" & x)
   end repeat


-----------------------------------------------'

Notice no mention of the do command.  This is what tripped me up.  I  
entered a BZ for it:   #2753
