What's the difference between CREATE PROC and CREATE PROCEDURE?

Question

I've scoured msdn and haven't found an answer. Is there a difference I should know about?

If there is truly no difference then why would this redundancy exist?

--SQL Server Stored Procedure Syntax
CREATE { PROC | PROCEDURE } [schema_name.] procedure_name [ ; number ] 
    [ { @parameter [ type_schema_name. ] data_type }
        [ VARYING ] [ = default ] [ OUT | OUTPUT | [READONLY]
    ] [ ,...n ] 
[ WITH <procedure_option> [ ,...n ] ]
[ FOR REPLICATION ] 
AS { [ BEGIN ] sql_statement [;] [ ...n ] [ END ] }
[;]

Same with DROP PROC

DROP { PROC | PROCEDURE } { [ schema_name. ] procedure } [ ,...n ]

Answer 1

There is no difference between the two.

Edit to answer your new question - there is no "redundancy" here, one is just short hand for the other. "Procedure" is a fairly long word, and people tend to like shortcuts for things. In the same way, "Exec" and "Execute" are the same.
