To all those who responded,
Thank you very much. The winner is grasshopper, because, although it is a little cumbersome, the Script Wizard does indeed produce ANSI text output.
The SQL Server 2000 script would generate an 'IF exists' clause that would DROP the SPROC and then CREATE a new one. IF we discover a way to append a drop Script and a Create script, we will have it made.
Thanks again to all who responded
