Copy Command Options

[modelmaker]

I have two questions regarding the 'copy' command:
(1) When I copy series between pages, the 'link' option doesn't appear to work:

Code: Select all

copy(link) annual\series1 quarterly\series1

(2) I am having trouble getting the 'smpl' option to work. The copy command seems to automatically merge any available data within the workfile range:

Code: Select all

copy(m,smpl="1970 2009") db1::series2 wf::series2

Thanks.

The link option is for creating database links, not links between pages. Use a link object if you want to create a link between two pages.

I'm not sure if the smpl option works when copying from a database.

With regard to the "smpl" option, I tried the following code:

Code: Select all

series series1 fetch(c=nu,d=db1) series2 copy(m,smpl="1971Q1 1990Q4") wf::series2 wf::series1

Even when copying within the same workfile page, the "smpl" option doesn't seem to work. Everything in series2 gets copied into series1. Any suggestions?

(Forgot to mention - I'm using EViews 7 Enterprise Edition.)

Seems to work for me:

Code: Select all

wfcreate(page=page1) m 1990 2010 series y=nrnd pagecreate(page=page2) m 1990 2010 copy(smpl="1993 1995") page1\y page2\y show y

Your code works, but why doesn't this code work?:

Code: Select all

wfcreate(page=page1) m 1990 2010 series y=db::lr series z copy(m,smpl="1993 1995") y z show z

The copy command isn't really meant for copying series into the same page. You can use simple = assignment to do that:

Code: Select all

smpl 1993 1995 series z = y
