Wondering, if you feed the "A" into a stringin and connect the
stringin to the Gensub?

I know I feed strings into gensubs in places.

Aloha,

Emmanuel,

You can't.  If a link's initial value is not entirely numeric,
EPICS will treat it as a PV name, rather than as a constant value
with which to initialize the value field associated with the link.
"Entirely numeric" means "completely eaten by strtol() or epicsStrtod()",
according to dbStaticLib.c's dbPutString().

Hello,

I would like to pass a CONSTANT char to gensub as an input parameter
(INPA).
record (genSub, "myGS") {
  ...
  field(INPA, "A")
  ...
}

How can I make gensub recognize A as a CONSTANT (and not as a PV
(CA_LINK))?
