How can I write and read mcu id location

For example : PIC18F458, its id location on 200000H to 200007H
How can I write to this location. Is that #id directive? But how can I write to these 8 bytes ?

How can I read this id memory? Which command should I use ?

Thanks

Use #id to put values in the ID locations. Then try this function to read it:

The Device ID only has two locations, as shown in the sample code.
But the "ID" has 8 locations. So you need to change the example
code to call it 8 times (instead of 2). Also, change the address so it's
for the "ID" location.

I have not tested these suggested changes in hardware.
