Well, you could do something like this (caution: untested e-mail Lingo)...
-- aList = #linearList or #propList
-- returns a #propList where
-- property is a value from aList
-- value is the number of occurrences of that aList value
on mListValuesCounts ( aList )
if not ilk ( aList, #list ) then return #error
tResultList = [:]
tList = aList.duplicate ( )
repeat while tList.count ( ) > 0
iVal = tList [ 1 ]
iCount = 1
tList.deleteAt ( 1 )
jIdx = tList.getPos ( iVal )
repeat while jIdx > 0
iCount = iCount + 1
tList.deleteAt ( jIdx )
jIdx = tList.getPos ( iVal )
end repeat
tResultList.setaProp ( iVal, iCount )
end repeat
tResultList.sort ( )
return tResultList
end
HTH,
