[TRNSYS-users] Fwd: Equation editor

Adnan,

   There is also an AND() function available. The function returns a 1 
if both the first and second arguments are 1. For instance:

zz = AND(x,y)

zz will be 1 if both x and y are 1.

There is a full list of functions in the 06-TRNEdit.pdf manual (section 
6.3.9.1)

kind regards,

  David
