i learn the code written by someone else has finished many years ago,and i couldn't contact with him.in the code ,i find the "now" programme,the defination and the example are easily understood,but i don't know which senario could use this keyword,which enviroment should "now" could be used. ,,the reference said ,in the same cycle ,and tcm is involved,but codes i read is something like this:
if ( (now @b_ev))
and (now @c_ev)
} ;//on brackets
i think the c_ev is the consequence,and the a_ev is the reason,,,this segment of code make me so confused!
thank you for your helping me out
