If I remember correctly, the alarm log and the current alarm history display
new alarm events (changes in alarm fields STAT and SEVR) as they happen.
Existing alarms are not logged when the alarm handler starts up because
they
are not new alarm events.
The -T command line option from DESY creates alarm log files with special
dated names which are automatically switched at midnight. This option must
conflict with the runtime log file name change option.
An -xml command line option was added to alh by SNS. If this flag exists
alh will use XML-ish format for log files and will print "XML!" to stdout.
If it is not present, alh prints "no XML!" .

There are several problems related to viewing / changing the alarm log
file. It actually crashes if I attempt to specify a new alarm log file:
Setup -> New Alarm Log File Name
============================
crconlnx1.als.lbl.gov% ./alh.sh &
[1] 32688
crconlnx1.als.lbl.gov% no XML!
*** glibc detected *** free(): invalid next size (fast): 0x0839e748 ***
./alh.sh: line 10: 32689 Aborted alh -f
/home/als/alsoper/alh -l /home/als/alsoper/alh/logs -global -m 0 -L -T
als.alhConfig
============================
The View->Current Alarm History shows a blank window even though there
are active alarms.
The View->Alarm Log File Window also seems to be missing items. Again,
there is a PV in major alarm that I would expect to see in the log file.
Is the 'no XML!' message important?
