|
–use [ROUTe:]OPEN (@ccnn) for a single channel;
–use [ROUTe:]OPEN (@ccnn,ccnn) for multiple channels;
–use [ROUTe:]OPEN (@ccnn:ccnn) for sequential channels;
–use [ROUTe:]OPEN (@ccnn:ccnn,ccnn:ccnn) for a group of sequential channels;
–or any combination.
Opening order for multiple channels with a single command is not guaranteed.
