Changing char length in stored procedures

Hello all, I'm using SQL Server 2000 and have about 250 stored procedures that use an EMPLID parameter or variable of type varchar with a length of 4. I need to change the length to 10 instead and would like to do so without having to open every sp for editing. Is there a way to do this through SQL Server 2000? Does anyone have a script to do this? Any help would be appreciated.I'd use SQL Enterprise Mangler to script all of the stored procedures, then a text editor to make the changes. It should be a simple replace operation, possibly using a regexp if you aren't careful about how you format your declarations.
