hi tarmo -

yes, same result as for you, with latest dev build.

my error message is slightly different:
error: syntax error, unexpected S_ADDIN, expecting T_OPCODE or 
T_FUNCTION or ',' or '='  (token "+= ") from file 
/home/jh/Desktop/test3.csd (1)
  line 13:
 >>>giCurrentEvent[0] +=  <<<

my code:
giCurrentEvent[] fillarray 1, 2, 3
giCurrentEvent[0] += 1
print giCurrentEvent[0]

with
giCurrentEvent[0] = giCurrentEvent[0] + 1
it works, as you say.

best -
	joachim
