Hi

See if GS Demo from http://www.oaltd.co.uk/Excel/Default.htm get you
started. It is Stephen Bullen's demonstration of circular references.

HTH. Best wishes Harald

Hello, How can I creat a circuit like logic function in excel? The
simplist
form would be like a logic latch circuit. Where an 'and' gate is used. One
of
the two inputs of the 'and' references a independent cell and the other
input
of the 'and' function is the output of the same 'and' function. In excel
this
creats a circular statement and excel doesn't like it. I am planning to
use
the DDE function and feed live data from an other application into the
Excel
spreadsheet and I want to use logic on the values perform complex, serial
data annalysis on it in real time. So, I don't know if one allows only one
iteration if it will work or not. Or if their are better ways of doing
this.
