Can a person take their old Epic D ISA files and use them with the USB version? If so how does one import them?

as far as I know they have to be rewritten. Some of the old commands have changed and the syntax certainly has.I started to write a new epl code for USB (because much of my cockpit layout has changed anyway) and found out that:1. my new code is much shorter that my old ISA code, because of the use of Epic Mapper2. the new epl syntax is more powerfull than the old and somehow more streamlined and3. it was fun to go back to solving those nasty little programing problems with nested if's etc...Hans
