Thanks for your reply.

I put the rule as below:

         $(A).SEVR    equals          MAJOR   or
         $(B).SEVR    equals          MAJROR  use     <A>B color>
         $(A).SEVR    equals          MINOR   or 
         $(B).SEVR    equals          MINOR   use     <A>B color>
         $(B).SEVR    equals          NO_ALARM   and
         $(A).SEVR    equals          NO_ALARM use     <B>A color>
         
and passed arguments to them: 
	A=XXX:YYY:Z:chan1Alarm,B=XXX:YYY:Z:chan2Alarm

But then when I activate the display dm "dies" (not possible to perform
any action on the display, besides killing it from WM)
Is there any limit concerning the total length of the arguments in the
line ?

Thanks for any comments.

Marian
