OK.

Attached is a patch file for dbScan.c which should fix the problem and
restore backward compatibility.

I have created (and quickly tested) it with EPICS 7 but I guess it
should work with 3.16 as well.

Please work against the 3.15 branch, since that was where we introduced
your named events work. We will merge it up into the later branches from
there.

The hack is to treat "x.000000" and "x" as the same event name if x is
an integer between 0 and 255. ("0" and "0.000000" are no event at all
now just like "").

I don't like the string comparisons since they would silently break if
the number of decimal digits generated by the double → string conversion
gets changed.

Better to parse the string properly into a double — look at the
epicsParseDouble() routine declared in epicsStdlib.h and documented at
https://epics.anl.gov/base/R3-15/5-docs/AppDevGuide/libComOSIlibraries.html#x21-84700020.13
— then either round or truncate the fractional part.

Thanks,
