EViews.com

Hi,

I have a problem with Eviews, and it might be due to the addin that i have made, but i am not sure...?

If you install the global addin addtospec with the command
'indexinstall
addin(type=global, menu = "adds new string in a system equation" , proc="addtospec", desc="adds new string in a system equation") "./addtospec.prg"

and if you run the program "problem_with_addin.prg" on the attached workfile, Eviews will close. But I do not understand why...?

Trying to find the error, I noted something interisting,

Eviews will close when running the program


delete ags_s
svector ags_s=ags.@svectornb
!r=@rows(ags_s)

'add instruments
for !k=1 to 10' "r
'finding country and industry codes in each equation
%var=@word(ags_s(!k),1)
!length=@length(%var)
%id=@mid(ags_s(!k),11, !length-11)
'add instrument
addtospec(k=!k, add= @ log(tfpr_{%id}(-2)) ) ags 'addin that adds a line to the system specification
next



however, if only running


!r=@rows(ags_s)

'add instruments
for !k=1 to 10' "r
'finding country and industry codes in each equation
%var=@word(ags_s(!k),1)
!length=@length(%var)
%id=@mid(ags_s(!k),11, !length-11)
'add instrument
addtospec(k=!k, add= @ log(tfpr_{%id}(-2)) ) ags 'addin that adds a line to the system specification
next


Eviews will not crash. I do not understand why...

Can you please help me

Seemed to work just fine for me. Which version of EViews are you using, and what is the build date?

Eviews 8, Jun 4 2014 build.

You might have to run it a couple of times before Eviews crashes.

Thanks for looking at this
Thomas

Now it worked with the code I gave you. But if you run the code

svector ags_s=ags.@svectornb
'add instruments
for !k=1 to @rows(ags_s)
' 'finding country and industry codes in each equation
%var=@word(ags_s(!k),1)
!length=@length(%var)
%id=@mid(ags_s(!k),11, !length-11)
'add instrument
addtospec(k=!k, add= @ log(tfpr_{%id}(-2)) ) ags 'addin that adds a line to the system specification
next

it will crash.

I tried it once more, when the loop goes from 1 to 10, and Eviews crashes again....

Got it. It is an issue when a parent program accesses a data member of an object, then execs a program that deletes that object. We'll see if we can get it fixes asap (although this one is tricky...)

excellent, thanks!
