Fell at the first hurdle!

OK so have started to get my head around how the thing operates but a % sign has me wondering what it does - certainly wan't any % signs around last time I looked at a bit of FORTRAN!

An example is:

LocVel(ibody) % u_ship = XX(v_index+1)

I have had to call up the really old boys club - my F-GURU - for an explanation. I wait with baited breath!

I also discovered I don't know how to use Google in all this which was an addition to the learning curve! Even the great G couldn't find a % reference for me!
