This is an ao record using SoftChannel device support
out-linked to a constant.
The problem appears to be that
dbPutLink( &pao->out, DBR_DOUBLE, &pao->oval, 1 );
in the soft device support code returns an error for a constant
link.
How do I say
if ( "link type is a constant" ) {
using the proper CA macros/structures?
