Question for WE 6.1.1 and 7.1.0.

How can I run another script from a script (craft script) in the same context? I need the functions from another script file to become available in my script without manually pasting the code of the second script into the first.

My trying in 7.1.0:

function include1(strfilename)
{
csc = new RhinoCraftScriptEngine();
csc.setTimeLimit(context.getConfiguration().scriptTimeout);
arvtmp = argv;

vars = new HashMap();
vars.put("argv", argvtmp);
vars.put("context", context);
vars.put("player", player);
csc.evaluate("", strfilename, player);
}

function include(strfilename)
{
filescript = context.getSafeOpenFile("craftscripts", strfilename, "js");
WorldEdit.getInstance().runScript(context.getPlayer(), filescript, argv);
}

Both function not working with errors (after this trying me should reload plugin, else all scripts not working):
