8. DATA INPUT/OUTPUT
When N–9998 is designated, N–9999 in (c) is automatically inserted
each time a file is input or output. This condition is reset by the
designation of (a), (b) or (c) or reset.
The same result is obtained both by sequentially searching the files by
specifying Nos. N1 to N9999 and by first searching one of N1 to N9999
and then using the N–9999 searching method. The searching time is
shorter in the latter case.
The ready signal (DR) of an input/output device is off.
An alarm is not immediately indicated in the CNC even when an
alarm occurs during head searching (when a file is not found, or
An alarm is given when the input/output operation is performed
after that. This alarm is also raised when N1 is specified for writ-
ing data to an empty floppy.(In this case, specify N0.)
