Opening stacks from variables

[Rodney Tamblyn]

Further to a recent thread on the list, I've been experimenting with 
opening stacks from variables.  One issue is how you refer to the stack 
after it has been opened.

Does anyone know of any issues with opening stacks from variables when 
compared to the conventional method of opening from a file?  Seems to 
work fine.

-- Script example
-- Binary read a stack file and create 4 example stack windows from the 
data
--

on mouseUp

   local tFile,tData,tStacks,x

   #read a stack in (binary)
   answer file "Select a stack file" with filter "MSTK"
   put it into tFile
   open file tFile for binary read
   read from file tFile until eof
   put it into tData
   close file tFile

   #note stack windows open.  There's no way to determine what the name 
of the stack
#being opened is so must compare against this list.
   put openStacks() into tStacks
   open stack (tData)
   #find out it's name
   repeat for each line x in openStacks()
     if lineOffset(x,tStacks) = 0 then
       put x into tStackName
       exit repeat
     end if
   end repeat
   #rename stack
   set the name of stack tStackName to "Example 1"
   #open a few more...
   repeat with x = 2 to 4
     open stack (tData)
     set the name of stack tStackName to "Example "&x
   end repeat
end mouseUp
