Hi Hinko,

You should also be able to replace the waveform record with an aSub record and
implement the sub-array replacement part in C code, which would need fewer
records on the IOC and is probably slightly more efficient, but will take more
development work to implement.

If I understand the use of aSub correctly, it does not need allow DTYP

being set. Since I can't bind any device to it, I was hoping that INPx

field(s) might be set to point to INST_IO based link type, something like :

@param(PARAM1=abc PARAM2=123)

but that does not seem to work as expected. The problem I see when

trying to get link value (this is from init() at IOC startup):

rec->inpa.value.instio.string ==>> '@param(PARAM1=abc'

 ONLY half of string.. where is the other half?

rec->inpa.text ==>> NULL

 NULL pointer ?

For other records such ai, bi, longin I can access INP field value using

'rec->inp.text'.

Thanks,
Hinko
