Brilliant thank you, that has worked great. Is it possible to do something
similar with the main prompt in default.js? 

"\x01-\x01c\xfe \x01b\x01h" + gettext("Main") + " \x01n\x01c\xfe \x01h" +
time_code +
		" \x01n\x01c[\x01h@GN@\x01n\x01c] @GRP@\x01\\
[\x01h@SN@\x01n\x01c] @SUB@: \x01n",

I can't see an exec for it in text.dat so assuming not quite as simple to
customise?
