Hi Dave,

You can try "Long String Field Modifier $" for your purpose.
Doc: https://urldefense.us/v3/__https://epics.anl.gov/base/R7-0/8-docs/doxygen/filters.html__;!!G_uCfscf7eWS!cnuappWtgqPWAx1TPmDXqDhMvigKvWKoFp2iYWd5Q8WjhwPeqNIiUSy188XGNI75gNbTE1TS62BgbrFUQfin8Q$ 

$ caput -S plain.VAL$ "this is a string longer than forty characters"
Old : plain.VAL$
New : plain.VAL$ this is a string longer than forty characters

$ caget -S plain.VAL$
plain.VAL$ this is a string longer than forty characters

I am also curious about how to do it through PV Access though...

Cheers,
Di
