I implemented improved alarm conditions in the alarm system. Now one can write
conditions like

  /Equipment/HV/Variables/Input[*] < 100

or 

  /Equipment/HV/Variables/Input[2-3] < 100

to check all values from an array or a certain range. If one array element
fulfills the alarm condition, the alarm is trigger. In addition, bit-wise alarm
conditions are possible

  /Equipment/Environment/Variables/Input[0] & 8

is triggered if bit #2 is set in Input[0].

The changes are committed to SVN revision 4242.
