Something like this, perhaps:

JString lockFileName = configuration->getValue (LockFileName,
LockFileNameValue);

if (lockFileName.IsEmpty())
{
gds__prefix_lock(buffer, LOCK_FILE);
lock_file = buffer;
}
else
lock_file = lockFileName;

I did that way (two years ago) so it would work both with a proper
configuration and the pre-Vulcan Firebird conventions defined in
jrd/file_params.h.

Now, I don't want to be too preachy or anything, but did it occur to you
to look at what the code already did before making your suggestion?
