State 1, Line 1 Incorrect syntax near ‘go’.

This stumped me for a short while. I had the following straightforward SQLServer batch:

if object_id( N'util.AllBatchProgress' ) is not null
    drop procedure util.AllBatchProgress;
go

and was taken aback when I hit this error when running it:

Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'go'. 

It looked absolutely fine to me; Go needs to stand apart from your SQL batch, on its own line, and here it does. 

But what’s this about line 1? How could this look like a 1 line? Ah, maybe if I'd copied it from Notepad++ (as I did) without realising the mode I was in, I'd have something like:

(this time with all symbols shown). I guess SSMS is not parsing those CR carriage returns -- should be CRLF. Converting the line endings to Windows format (again in Notepad++) got it working.
