What does your $$$AssertEquals macro do?

Both that macro and your WriteCapture classmethod get turned into INT code at some point, and you can view this from Studio if you make sure class compilation preserves INT. Maybe if you post the relevant INT fragments here someone will be able to spot why the presence of $$$AssertEquals is breaking things.

Since 86400 is the number of seconds in one day, did you mean to write "it will run every day" rather than "it will run every two days"? Or have I misunderstood something?

It'd be easy enough to write a method that notes the current collation of locals for the process - ##class(%Library.Collate).GetLocalNumber() - and if it's not 5 (the number for "Cache standard") then temporarily set it - ##class(%Library.Collate).SetLocalNumber(5) - before doing the ]] test, then reinstate the noted collation if necessary.

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.

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:

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.

Nancy, to help with DC housekeeping, please re-post your comment as an Answer, then set the checkmark against its title so your original question disappears from the "no answer" and "unanswered" views.

I guess I could add a little backdoor into this method as well; a screen door, if you will, on my back door.

A smart catflap?

I have just posted an article here about how to determine whether a class is mapped.

Thiago, maybe re-post your Comment as an Answer. That way the OP can set the checkmark alongside your answer, so the question no longer lists as "unanswered". Plus, you get credit.

Tom, maybe re-post that information as an Answer rather than a Comment. Then you can accept your own answer (set the checkmark alongside it), so your question no longer lists as "unanswered".

AFAIK we users aren't able to change increase this value. If we could, we might be tempted to set it to a very large value

See [@Robert Cemper]'s answer for how you can decrease it.
