Subject:	Dynamically changing HIHI PV field

Hello all.

I have an equipment which has the HIGH field configurable in the hardware. We already have a PV that reads it, but it is currently an entire PV, and not a field of another existing PV.

Im trying to get that PV result and put it in the HIGH field of another PV. Something like:

record(ai, "MY:PV") {

field(HIHI, 10)

field(HIGH, "ANOTHER:PV:HIGH:LIMIT PP")

field(LOW, -1)

field(LOLO, -5)

field(HHSV, MAJOR)

field(HSV, MINOR)

field(LSV, MINOR)

field(LLSV, MAJOR)

}

but each try of mine gets either syntax error or 'Can't set "MY:PV.HIGH" to "ANOTHER:PV:HIGH:LIMIT"'. Am i doing something wrong? Is this approach even possible?
Thanks in advance for any help.
