X11 & 64-bit Compatibility

[robert downes]

Our work just upgraded to EViews8 from Eviews5.

We have workfiles with the census X11 seasonal transformation being called, with no issues until today. After upgrading the following message occurs:
"X11, as provided by the U.S. Census, is not supported on 64-bit operating systems. Please use X12 instead in......"

I don't see any mention online or this forum regarding 64-bit and X11. Any help would be appreciated. Thanks in advance.

There is nothing to add. X11 was written 45 years ago. It is not 64bit compatible.

I don't understand how X11 was 64-bit compatible before, but not now. The CPU hasn't changed, only the version of EViews.

Thanks for the quick reply.

I assume you upgraded the version of Windows too. It has nothing to do with the version of EViews. It is all about the version of Windows. X-11 won't run on 64bit Windows.

Thanks EViews Gareth.......
Do you see any potential issues with running the 32-bit version of EViews with 64-bit Win7?

[EViews Gareth]

No, other than the fact that X-11 won't work.

Now a related question - can .x12 function be saved to an existing series that doesn't have an EViews specified extension?

I can run kunrtu.x12 but don't know how to save adjustments without EViews adding _sa to a new series

E.G.: previously the code we used for seasonal adjustments: x11(m) kunrtu kunrt -> this performed a seasonal adjusted on kunrtu with results saved in the series kunrt. Using kunrt as the "base name" still adds the _sa extension onto the series.

Now, I need to save seasonal adjustment for kunrtu.x12 as kunrt. I can't rename kunrtu_sa as kunrt because it already exists

Also, there are numerous series that this applies to, so using wildcards (*_sa) would be best if at all possible. Each variable being seasonally adjusted has 'u' as its last letter, so a wildcard such as *u_sa should catch all of the adjustment.

Can you simply delete kunrt, then rename?

[robert downes]

There are a couple of issue I see with deleting each:
1) there are a decent amount of series that would need to be deleted
2) deleting would have to be done each time the program is run - even if it was written into the program, it seems a bit superfluous

Alternatively, simply using the _sa would result in just as much work as other programs & models call on these series.

I'm not sure there's a better way than deleting.
