Concatnate long statement

[phimtau123]

hi how do you concatenate long statement in perl? for example my long assignment code.

my ($eqpid, $chamber, $lotid, $wafer_flow, $recipe, $wafer_slot, $step
+_value, $alarmtype, $sensor, $signal_level, $alarm_upper_limit, $alar
+m_lower_limit, $code, $date_submited, $time_submited, $filenames,$use
+rcode, $sock)=@_;
