While a tape is running, a program input from an I/O device connected
to the reader/punch interface can be executed and stored in memory.
Similarly, a program stored in memory can be executed and output
through the reader/punch interface at the same time.
With the retrace function, the tool can be moved in the reverse direction
(reverse movement) by using the REVERSE switch during automatic
operation to trace the programmed path. The retrace function also enables
the user to move the tool in the forward direction again (forward return
movement) along the retraced path until the retrace start position is
reached. When the tool reaches the retrace start position, the tool resumes
movement according to the program.
