Commands
The Verify Device command compares data in a programmed device with data
in RAM. Depending on the type of device selected, either the Verify Logic
Device screen or the Verify Memory Device screen appears when you select
the Verify Device command.
Before you can verify a device, you must load the data into RAM. For more
information, see page 4-8.
