Example Ocean measurement file in ADEXL

I'm trying to create an ADEXL measurement using an Ocean script and I'm not having a lot of luck.  I've been trying to find a simple example but I've yet to see one in the manual or online.  

Right now I'm just trying to get something very simple to work.  For example, I have a regular measure expression 

if(((VAR("trace0") == 0) && (VAR("trace1") == 0)) 4 0)

which works just fine.  If I take this code and plug it into a file and then tell it to use this file as an Ocean script I get an "eval err".  Is there some special format I need to use within the ocean script to get it to work with ADEXL?

 I'm presently using IC6.1.5-64b.500.132

Thanks
