How to compile in earlier versions using new keywords?

[Monte Goulding]

One solution I have used for this is chained behaviors:

on mouseUp
   put GetWord(fld “IN”,1) into fld “OUT”
end mouseUp

— parent behavior won’t compile in LC 6
function GetWord pText, pWord
   return trueword pWord of pText
end GetWord

— grandparent behavior
function GetWord pText, pWord
   return word pWord of pText
end GetWord
