Re: Nested Arrays

[Rob Cozens]

Is it possible to create nested arrays of the form A[X[i]] or 
deeper?  I tried but it doesn't seem to be working.
This is unfortunately not supported (yet?)...
Greg, et al:
If you can live with notation like "A[X,i]" instead of "A[X[i]]", you 
can use discrete keyed variables:

on initializeArray @theArray,xBound,iBound,initialValue
   repeat with X = 1 to xBound
      repeat with i = 1 to yBound
          put initialValue into theArray[(X&comma&i)]
      end repeat
    end repeat
end initializeArray
function getElement @theArray,xBound,iBound
    return theArray[(xBound&comma&iBound)]
end getElement
on setElement @theArray,xBound,iBound,elementValue
    put elementValue into theArray[(xBound&comma&iBound)]
end setElement
Actually, if something like
   get "X[i]"
   put someValue into keyedVariable[it]
works,  you could even maintain "A[X,i]" syntax.
There is a set of generic array handlers in Serendipity_Library 
<http://wecode.org/serendipity/serendipity_downloader.htm> that 
support n-dimensional arrays, including array math and matrix math. 
However my array-processing handlers have proven to be slower than 
using keyed variable references as above.
