Re: [pilot-db-list] Calculated feature on DB

[Scott W. <swa...@my...>]

If the script.txt file did not get included with your download of 
pilot-db, get a copy from the sourceforge repository:

	http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/pilot-db/db/docs/

this will tell you just about everything you might want to know about 
scripts.  But the short answer to your question is:

	say field 0 and 1 are numbers (e.g. Integer, floats, boolean)

	then the script for field 2 would be:  (- %1 %0)

note that fields are zero indexed when they are referenced in the script 
with the '%' symbol.
