Bug when "copy" from a closed workfile

[johansamuelsson]

In many of our calculationsystems we copy data by reading directly from a closed workfile, for example

Series x = C:\Temp\Test.Wf1::A\y

In the latest version, Eviews seems to open the workfile when this command is used.

Some systems are huge and Eviews gives an error message when Eivews has opened 30 workfiles. The error message is also a bit wrong.

The following code works in Eviews12 and in Eviews13 Dec 28 2022 build, but not in Eviews13 Jan 19 2023 build

Code: Select all

Shell If Not exist C:\Temp Md C:\Temp For !i = 1 To 40 WfCreate(page=A) a 2000 2020 Series a{!i} = @rnd WfSave C:\Temp\Test{!i} Close @All Next WfCreate(page=A) a 2000 2020 For !i = 1 To 40 Series b{!i} = C:\Temp\Test{!i}.Wf1::A\a{!i} Next

Thanks for the bug report.

This will be fixed in the next patch.

A possibly related bit of info.
We are also having our code fail in Eviews 13 (Jan19 build), where it's solid in Eviews 12.

This code bit runs fine in Eviews 12.

Code: Select all

wfuse %filepath1 wfopen %filepath2 copy(o) %filepath2::* %filepath1::

Where %filepathX is a full path like "C:\work\fileX.wf1"

In Eviews 13 it would run, but result in everything getting closed, and the next meaningful Eviews action shuts down the application. If the next action happens in the code, Eviews quits as well.

The following tweak appears to work though

Code: Select all

copy(o) %filestring2::* %file1::

Where %file1 is "file1"

Updated to the most recent release of Eview13, and the issue is still there.
Any help?

Hi, the problem with the "Maximum number of Workfiles" seems to have returned.

When I run the code below, I get the error message

Maximum number of Workfiles are already open
in "COPY C:\TEMP\TEST31.WF1::A\A31 A\B31" in
Test.PRG on line 11.

Is there any suggested solution?

Eviews 13: Standard Edition - May 7 2024 build. Same error message in Eviews 14: Enterprice Edition - Jun 10 2024 build
