Greetings all,
I am unable to write an array with pvxput.  I'm hoping that I'm using 
the wrong syntax.


"pvxput" from current releases of PVXS have only limited support for put to scalars.  This is why I still recommend sticking with "pvput" from pvAccessCPP.

However, if you would like to test:

https://github.com/epics-base/pvxs/pull/63

would add support for JSON style assignments.  eg.

pvxput pv:name "[1,2,3]"

pvxput pv:name "value.colA=[1,2,3]" "value.colB=[1,2,3]"
