Check for no value in a local variable

How can I check the value of a local variable to see whether it reurned
a record after setting it to a SELECT Query?
I also need to be able use the value as an integer if it finds a match
Declare @.Found as Int
SET @.Found= ( SELECT TOP 1 ID FROM tbl WHERE col1=@.col1 AND col2=@.col2
)
IF @.Found ' -- how to test for no match found
