    i think you can just see if its a reference... ie... use the ref()
built in function.  will return "" if it is not a reference and when i
tested this,
it returned DBI::db for DBI connections to both sybase and SQL server.

	Sorry, this is not a sybase-specific question, but DBI... 

	I'm writing a function that I want to be able to pass either a
Sybase server name or a DBI dbhandle; if the former, it will establish a
connection to the server; if the latter, it will use the extant
connection. Is there a straightforward way to check to see if the value
passed to the function is a DBH or not?

	Thanks, 

	Steve
