link statement ignored if illegal characters

[rousing]

Hi

When using the fetch command ie. fetch(d="DS_DB",link,c=l) USE$EF.. with a ticker containing illegal characters, it appears that the link does not get created.
Thanks in advance for your help.

I'm also having problems with links in Eviews 9. This code works in Eviews 8 (Annes grade is 2 in year 3) but in Eviews 9 I only get NA for all observations:

Code: Select all

WfCreate C:\temp\test u 4 Pagerename untitled p1 series year = @obsnum alpha Name Name(1) = "Jane" Name(2) = "Bob" Name(3) = "Anne" Name(4) = "Pete" Series grade = 2 PageCreate (page=p2) u 4 series year = @obsnum link AnnesGrade AnnesGrade.linkto(c=unique, smpl="if @upper(Name)=""Anne""") p1\Grade @src Year @dest Year

ErikG:

Your issue looks like a bug in 8, not 9. Your sample IF condition explicitly states:

Code: Select all

if @upper(name) = "Anne"

which (if done correctly), will never be true as "Anne" is mixed case and @upper of anything will always be uppercase only.

You are correct in saying this works in 8 and I'm not sure why. In fact, in version 8, if I switch back to the first page of the workfile and type in:

Code: Select all

smpl if @upper(Name)="Anne"

into the command window, EViews 8 correctly states:

Code: Select all

Warning: Sample contains no observations.

In any case, this "bug" has been fixed in 9 which is why you're seeing different behavior. You should change your if condition to be:

Code: Select all

smpl if @upper(Name)="ANNE"

or

Code: Select all

smpl if @upper(Name)=@upper("Anne")

to perform the match correctly.

Rousing, I'll look at your issue next...

Thanks, it could be that it is isolated to datastream fetches

Rasmus:

I tried importing a series object with the name "y1$test" from an EViews database, and it seemed to import ok and the link was created fine.

Which illegal character were you trying to import? And which database was the source? Can I get a copy of this database (if it's a file)?

Rasmus:

I tried retrieving your "USE$EF.." object from DataStream and I get a linked series object whose name is: USE$EF__

and the link seems to exist. I can update just fine. I did this via both command window and via a program and the results were the same.

Are you doing anything different?

It looks like the most recent patch has taken care of the problem :) - just tried with an old version Apr 3 2015 build (I have not updated so frequently at home - and here the issue remained) - after updating to the latest patch the problem is gone (so the issue must have been addressed after the Eviews 9 May 27 2015 build - which I was using at work at the time)
Anyways, thanks a lot for your help :)
