You are on the right track.
If the string came into dr:scalc.AA
(where is dr:scalc an scalcout record),
then use dr:scalc.CALC = "$S(AA,'%lg')"
to extract that result.

I'm using an Asyn record to get a readback from a Kepco power supply via
GPIB. The return string comes back as an exponential, i.e. "1.5439E01".
Is there a slick way for taking this string and decoding it into a
float? Will the SSCANF facility in the SCALC record do this?
Thanks...
