The program does not terminate

Attempt to add a _DISPLAY statement after each PRINT, and tell me how that affects things on your system.  If it changes anything at all.

 No, it doesn't change anything.

Certainly, it seems to depend a lot - indeed, very much - on the date format of the system (which each regional version of Windows has) that one is trying to manipulate and impose on the system itself.

With PowerShell, it is possible to determine what it is, but it seems that it doesn't work the same way. Perhaps the CMD commands work better, but it would still be preferable to use PowerShell.

In any case, this does not explain why version 3.12 of QB64 poses absolutely no problem and does not cause any errors with the code syntax, while later versions - on the same machines - do not behave as one would expect.
