Re: sCalcout - again

[Kurt Goetze <goetze@aps.anl.gov>]

Hi Pierrick,

INAA, INBB, etc. are input links, you will want to set your strings 
("Dry", etc.)
in the corresponding .AA, .BB ... fields.  SVAL will contain the string 
result of
the calculation, so you don't want to try to force a PV name in there.  The
stringout's PV name should go into the scalcout's .OUT field, in which case
you will not need to forward link to the stringout record.

hth,
Kurt
