Re: Clarification on aliases and the .NAME field

[Andrew Johnson <anj@aps.anl.gov>]

Hi Murali,

Your assumption is correct for CA servers that are real IOCs, the .NAME field should always give you the canonical record name when you're actually using an alias name. However a server that uses the PCAS could do whatever it wants with the PV name, it doesn't have to support the .FIELD syntax which the IOC uses.
