Checked the "Easytrieve Language Support for Visual Studio Code(Program Modifications)" on Youtube.
It seems that the following 3 functions do not work properly.
1. Hover
2. Go to definition
3. Autocompletion(Ctrl+Space)
Release : 6.4
Component : Easytrieve Report Generator for Windows
The easytrieve-0.1.3.vsix file was created as a solution.
But, planning to release these fix with our next level set ptf which will have some other changes as well.
Contact the Easytrieve engineer if you need that file.
