checksum and MPLAB

I used UltraEdit as my IDE and have not used MPLAB. I would like to purchase some PICs from microchip already programmed, but microchip suggests I supply the MPLAB checksum. Does anyone know how to do this?

If I open MPLAB and tell it to load my .lst file then it shows a checksum at the top of the screen, is this what microchip wants, or something else?

Thanks
Ringo

You should ask them, but I think they want you to do this:

1. Open MPLAB and close any workspace that you have open,
so it's an empty workspace.

2. If the Checksum toolbar is not visible, go to the View menu
and then to the Toolbars menu and make it visible.

3. Then go to the Configure menu and then to Select Device, and select
your PIC. This step is essential.

4. Go to the File menu, and use the Import function to import your HEX
file. The checksum for the Hex file should appear in the Checksum
toolbar.
