DEFAULT_CHANNELS

DEFAULT_CHANNELS <nbr of I/O channels>

DEFAULT_CHANNELS changes the number of I/O channels assigned to a file with ctDUPCHANEL in its file mode at open, unless the file is in the SET_FILE_CHANNELS list. The default number of channels is not limited by the NUMCHANEL value.

Note: Multiple I/O channels are disabled for newly created files. The multiple I/O channels take affect only on an open file call. Also, depending on the default number of I/O channels, a superfile host not in the SET_FILE_CHANNELS will use no more than 2 * NUMCHANEL I/O channels.
