This is a good point. I was relying on the doc at http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=... being correct when it says:

Binary Sorts after tests whether the left operand sorts after the right operand in numeric subscript collation sequence. In numeric collation sequence, the null string collates first, followed by canonical numbers in numeric order with negative numbers first, zero next, and positive numbers, followed lastly by nonnumeric values.

How about using the "sorts after" operator  ]] for this?

USER>w "0.12345"]]$c(0)
1
USER>w ".12345"]]$c(0)
0

There's a hyperlink at the top of part 2 above. Maybe it wasn't there when you first looked.

Per the OP's comment here, in this case it's an 8-bit Caché instance, so Unicode characters aren't available on the server.

Yes, that's a DC limitation at the moment. One workaround is to copy the link from the hyperlinked word "Comment" at the foot of whichever comment you consider to be the answer, then add a new answer that references this, e.g.

Answered by this comment.

Then you can accept your own comment.

Uri, I assume your two references to %GSIZE above are supposed to say %GSET.

ISC published information about %GSET the past, and documented it being renamed to %SYS.GSET at 5.1. I think it's a pity they now consider it only to have been 'internal'.

Are you running a Unicode version of Caché? If you're not sure, post your $ZVERSION string here.

Uri, when you get an answer from WRC please come back here, post it as an answer to your question, and set the checkmark against your answer so the DC question shows as "answered".

I suggest you contact WRC about this.

Good to hear Rubens helped you Coty. The best way of giving him due credit on DC is for you (as OP) to set the checkmark alongside his answer. Look for it above, in the area I've highlighted in my screenshot below:

A sort of warrant canary.

I don't see an ISC Staff indicator as meaning the post is inherently more valuable or more reliable. Rather, that a lot of posts are by people without that indicator, including posts that get lots of positive votes. I think this could help counter any impression that DC is some kind of "WRC-lite".

What Caché version are you seeing this on Sean?

I previously posted a request for display of which participants are InterSystems staff:

Currently we don't seem to have a good way of reminding/encouraging the OP to accept answers. If we add a suitable comment to their post, this means everyone gets the impression there's new information on that post, which rises to the top of the "most recent" list.

Maybe DC could periodically send each user a list of their questions that have at least one answer but none yet accepted.

Please give us more context. Where is the question arising from? It looks a bit like a homework assignment after a class covering a specific area of the COS language.
