[Resolved] SQL2k Scope Problem

Morning, all. Got this problem and can't figure it out - must be missing something extremely simple. Here's the code:

VB Code:

create function IncAlpha
    -- Increments a single alpha character
    -- uses this sequence ABCDEF..Z
    (@Alpha char(1))
    returns char(1)
as
    begin
        
        declare @RetVal char(1)
    
        if @Alpha is null or @Alpha=''
            set @RetVal='A'
        else
            set @Retval= char(ascii(@Alpha)+1)
 
        return @Retval
 
    end
go

When I try to compile the function it raises an error on the 'return @Retval' line saying that I must declare it:

VB Code:

Server: Msg 137, Level 15, State 1, Procedure IncAlpha, Line 17
Must declare the variable '@Retval'.

What exactly am I doing wrong, here?

Is is case sensitive RetVal / Retval ?

Yes it was - many thanks for helping me, aka the village idiot. Now I'll just have to rebuild the server and take the binary collation off. Don't trust them techie guys, chaps.

Don't trust 'em: Do it yourself.

Many thanks again. Cheers :)

I have never used a server that was case-sensitive - what a nightmare that must be!
