> Is the FLNK limited to 40 chars?
No.
What's limited to 40 chars would be TheNewLinkValue if you write it like this, which sends the value as a it as a DBF_STRING:

   caput record.FLNK "TheNewLinkValue"

But you can write it as a byte waveform by using record.FLNK$ as a channel name.

The only limitation should be related to the record name based on
dbDefs.h:#define PVNAME_STRINGSZ 61
