Mike: No luck with that either. Also tried to use Datenum but that 
doesn't work either.

What I am trying to backtest are Buys and Sells, but only if they 
occur (for example) in 1998.

This is achieved without problem using the range control, but I can't 
get it to work using a date function in the afl.
