You can actually test for anything that resolves to true or false.

put (the width of this stack div 2) > 154 into testValue

put the locktext of fld 1 into testValue

get the script of this stack
put the number of lines in IT into testValue

switch testValue
      case true

----------------------
put the textcolor of fld 1 into testValue

switch testValue
    case "red"
    case "yellow"
    case "orange"
	put "red" into newFontColor
         break
    case "green"
    case "blue"
    case "purple"
	put "green" into newFontColor
         break
    case (testValue is among the words in "pink coral azure maize")
         put "darkBlue" into newFontColor
         break
    default
	put "black" into newFontColor
end switch

set the textcolor of fld 1 to newFontColor

Hope this gives you many ideas.
