I use these, an easy and modular approach:
on setCustomProp pObjRef, pPropSet, pProp, pValue
-- modeled after deleteCustomProp
-- not sure where this comes from
put the custompropertyset of pObjRef into oldPropSet
set the custompropertyset of pObjRef to pPropSet
set the pProp of pObjRef to pValue
set the custompropertyset of pObjRef to oldPropSet
end setCustomProp
function getCustomProp pObjRef, pProp, pPropSet
-- modeled after deleteCustomProp
-- not sure where this comes from
-- if pPropSet = empty then uses the default custompropertyset
put the custompropertyset of pObjRef into oldPropSet
set the custompropertyset of pObjRef to pPropSet
put the pProp of pObjRef into tValue
set the custompropertyset of pObjRef to oldPropSet
return tValue
end getCustomProp
on deleteCustomProp pObjRef, pProp, pPropSet
-- not sure where this comes from, it's not mine
-- thanks to <whoever> !
put the custompropertyset of pObjRef into oldPropSet
set the custompropertyset of pObjRef to pPropSet
put the customkeys of pObjRef into keysList
set the wholematches to true
put lineoffset(pProp,keysList) into propLine
if propLine <> 0 then
delete line propLine of keysList
set the customkeys of pObjRef to keysList
end if
set the custompropertyset of pObjRef to oldPropSet
end deleteCustomProp
