Hi David,



[quote="You"]I wonder however, could you not equate the 'field labels' as index offset constants and then use the regular index routines?
[/quote]Yes and so I did.
I have abandoned the index and named routines all together
so now I have only 4 [u]byteindexed[/u] routines and 2 macros.
The byteindexed routines do not double the index so they
can be used even if an array supports wordfields and bytefields.
The 'problem' with fieldaddresses is that they are absolute and
not relative to the arraybegin. To support multiple instances
of identical objects (like sensor1 and sensor2 in the demo)
not only the address of the instance but also the address of
the object definition must be given.
I have resolved that using two macros GET_VAR and PUT_VAR
that you call like this:

\GET_VAR resultName,objectName,objectField,objectInstance
\GET_VAR objectName,objectField,objectInstance
\GET_VAR resultName,varName
\GET_VAR varName

\PUT_VAR objectName,objectField,objectInstance,value
\PUT_VAR objectName,objectField,objectInstance
\PUT_VAR varName,value
\PUT_VAR varName

Check out the generated code in the list view.
The subroutines do not yet suppoert spanned banks on the sx18/20/28.
