Hi,
I am writing a aSub routine to do some multiinput-multioutput data analysis.
In some cases, I do not want to update the output links. e.g. let those
OUTA-OUTU PVs values untouched.
If I do not do anything to the prec->vala to prec->valu, the corresponding PVs still get updated, but with some default values, e.g. 0.0 for DOUBLE.
I also tried to set effective length (e.g. set neva=0), but it did not work for an ao record.
Is there anyway skip updating any/some of the output PVs in the aSub routine ?
Thanks.
