Thank you for your post.
Get (FoundCount) returns the number of records in the current found set. Therefore, a possible script would be:
Set Variable [ $foundcount ; Get (FoundCount) ]
Omit Multiple Records [ No dialog ; $foundcount ]
Let me know if you need additional clarification.
You might want to precede those steps with Go to Record/request/page [first] just in case you current record is not the first record.
You can also perform a find using criteria that will never match any record such as specifying a negative number in a serial number field that started with zero when assigning values. set error Capture [on] can keep the "no records found" dialog from popping up in the middle of your script.
and for single user databases, this script has long been used, but I can't recommend it for databases being actively edited by more than one user:
Show all Records
Show Omitted Only.
