Backup Stored Procedures

Script from a colleague.
This could be scheduled to backup code.
Particularly useful in development environments -


CREATE PROCEDURE dbo.StoredProcBackup_sp

@DestinationDir as varchar(200) = 'D:\SQLDATA\MSSQL\BACKUP\StoredProcedures\AND THE REST OF YOUR PATH',
@User as varchar(20)= 'USER',
@Password as varchar(20) = 'PASSWORD'
AS

set nocount on

declare @Error int
declare @RootDir varchar(210)
declare @RootDay varchar(215)
declare @CheckDircmd varchar(300)
