Okay it's not entirely straight forward. I took a simple array from a datagrid 
with one record and ran this on it:

on mouseUp pButtonNumber
   put the dgData of group "dgsites" into aSiteData
   put arrayencode(aSiteData) into tSiteData
   repeat for each char tChar in tSiteData
      add 1 to tCounter
      if cleanAscii(tChar) is not empty then next repeat
      put tCounter & tab & charToNum(tChar) & cr after tAscii
   end repeat
   set the itemDelimiter to tab
   sort lines of tAscii numeric by item 2 of each
   put tAscii
end mouseUp

This returns a tab delimited list of position and non-printing ascii characters 
ranging from 0 to 58. What the ascii characters designate is the mystery. Any 
documentation on that?
