Recomend this type of approach in the preamble
Paul
///////////////////////////// Begin Preamble \\\\\\\\\\\\\\\\\\\\\\\\\
function getLibrary(libraryName)
{
var libraryPath;
var scriptsHere = __FILE__.lastIndexOf("/scripts/");
libraryPath = __FILE__.substr(0,scriptsHere) + "/scripts-library/";
// /script-library/ is a sibling to /scripts/ just below /config/
var thisLibrary = libraryPath + libraryName +".js";
thisLibrary = thisLibrary.replace(/\//g, '\\'); //MS Windows Specific
var libraryOpened = TW.app.openFile(thisLibrary);
var Js = libraryOpened.text
libraryOpened.close();
libraryOpened = null;
return(Js);
}
// sucessive libaries can be called this way.
eval(getLibrary("const_hello"));
// e.g. eval(getLibrary("const_second"));

So perhaps this will change (which would mean that existing scripts that INTEND to display a result by returning it will have to be changed to use TW.information or similar).
