OK so I was getting cocky.

I normally only use DSQL when I create the SQL on the fly,
so it is always re-prepared before executing. I'd tidied up
the alarm loop and added the parameter instead of changing
the SQL, and forgotten I had changed it. BeyondCompare is a
godsent, isn't it.

I've done a check, and all the other DSQL is still 'on the
fly' so fingers crossed we are there.
