RE: CHKDIR command

[Soapbox opinion]
I am the tech world's number one skeptic on AI. The first AI demo on Google should have put the kibosh on it for at least a decade.
It produced six images of American "founding fathers". Five of them were presented as in various shades of black, and one was presented as an native Indian complete with headdress fit for a chief.
Google took it off pretty quick. And subsequent attempts by them and others *seemed* more accurate, except AI has hallucinated all kinds of fiction, presenting lies as if it were a result of search.

I think ALL computer-generated text and images should be 100 percent open-source. As a disclaimer I think copyright and patents in general are not ethical. It's not material property. The laws gave Thomas Edison more prominence that Nicolas Tesla until the Internet exposed the shame. Then the patent office illegally confiscated one of Tesla's patents to Marconi because the payout was less (cretins!) and only after its worth dropped and a long lawsuit did they correct the "error".
And now we have Microsoft and Apple doing legal agreements to share "intellectual property" for copyrights that are obvious (like a coding algorithm for matching country codes to the country it belongs to.

We upgraded to 7.5 with the latest cume and TRs last month. WRKOBJ OBJ(*ALL/CHKDIR*) returned only CHKDIRE in the TAATOOL library.

Subject: CHKDIR command

my man Grok is insisting that the CHKDIR command exists on the IBM i. Is
that true?

here is what Grok says:

Since you're on IBM i 7.5 (V7R5M0) and the CHKDIR command is not found, that means your system does not have the required Technology Refresh (TR) level installed yet.The CHKDIR command was introduced in relatively recent
TRs:

- IBM i 7.5 → first available around TR2 or TR3 (late 2022 / early 2023
timeframe)
- IBM i 7.4 → TR5 or TR6

Many 7.5 systems shipped initially without the latest cumulative PTFs or group PTFs, so CHKDIR is missing until you apply the appropriate PTFs.

Google AI says no:

IBM i does not have a native, IBM-supplied CL command named CHKDIR to check if an Integrated File System (IFS) folder exists. Instead, developers commonly use the CHKIFSOBJ...
