The HR Key is used to specify both the AR and HR Areas, the CNT Key is
used to specify the entire timer/counter area, and the DM Key is used to spec-
ify the DM Area.
It is also possible to retain a portion of the Program Memory from the first
memory address to a specified address. After designating the data areas to
be retained, specify the first Program Memory address to be cleared. For
example, input 030 to leave addresses 000 to 029 untouched, but to clear
addresses from 030 to the end of Program Memory.
As an example, follow the procedure below to retain the timer/counter area
and Program Memory addresses 000 through 122:
1. Press the CLR Key to bring up the initial display.
2. Press the SET, NOT, and then the RESET Key to begin the operation.
3. Press the CNT Key to remove the timer/counter area from the data areas
shown on the display. (Counter PVs will not be cleared.)
4. Press 123 to specify 123 as the starting program address.

The I/O comments function has been enabled for the CPM2C-S accompany-
ing the CX-Programmer upgrade from version 1.2 to 2.0. This operation is
used when it is necessary to clear the I/O comment area along with the rest of
memory. The contents of the I/O comment area are completely initialized, and
the size of the area is returned to its initial value of 2.0 Kwords.

SET NOT RESET
This operation is required in order to initialize the I/O comment area along
with the program. The memory clear operation (refer to 8-2-2 Clearing Mem-
ory) does not initialize the I/O comment area.
The I/O comment area and ladder program area capacities can be read by
reading UM allocation data when the I/O comment area has been set with the
CX-Programmer (version 2.0 or later). To change the size of the I/O comment
