Myrna van Lunteren updated DERBY-2255:
--------------------------------------

    issue.field.attachment: DERBY-2255_4.diff

I refreshed the patch (because various changes have gone in to utilMain since the last posting), then tried the two versions of StatementFinder.readSingleLineComment (as per attachements _2 and _3.diff).

But I found strange behavior with the code of _3.diff; a commented line, (i.e. starting with --) followed by a return, would result in a line without a prompt.
Hitting return again, would give me a prompt again and I could go on...

When I used the code of _2.diff I saw no such problem; no 'getting stuck' in comment mode...

I have no access to a Mac, is there someone who does & can  reconfirm this patch?

> Many users have been confused by the lack of response from ij when they forget to end a statement with a semicolon, and believe that Derby is taking its sweet time answering their query, while ij is simply waiting for more input.
> This issue tries to address this by adding a short "> " prompt to the next line after a newline has been entered by the user without ending the statement with a semicolon.
