Does your record contain a field with a unique ID such as an auto-entered serial number? If not, define one and use replace field contents to update your current records with a serial number. Once you've done that, you don't even need to have this field visible on any layout.
Now you can use the current record's serial number in find to isolate this one record:
Assuming serial number field is called "ID"...
Set Variable [$ID ; Value: YourTable::ID ]
Enter Find mode 
Set field [YourTable::ID ; $ID ]
If you aren't hosting this database over a network, you can also use this code to isolate the current record:
Show All Records
Show omitted only
I don't suggest this in a multi-user environment, because there's a small chance that another user could create a new record at the same time this script runs and then show omitted only could pull up that new record along with the one your script omitted.
Phil, you are the man. Many thanks.
