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(). -- Tim Mooney ([email protected]) (630)252-5417 Beamline Controls & Data Acquisition Group Advanced Photon Source, Argonne National Lab.

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))? -- Emmanuel
