and the failing example is
BL09.0%PLC%BM00%EPS
The character "." is a special one in EPICS because it is used to
separate the record name and field name.
When dbFindRecord is called it does:
while (*precordName && (*precordName != '.') && (lenName < PVNAME_SZ)){
*pconvName++ = *precordName++;
lenName++;
}
i.e. it's looking for the "." as the end of the record name, so that pretty much
makes "." a character to avoid in pv names. ":" and "_" work in names--could you
possibly substitute one of those. It doesn't look like anything else is illegal,
but I wouldn't put money on it just yet. And don't forget the limitation on length.
