VSCode BBj Language Support extension does not meet minimum code completion standard described in BASIS documentation

[mphelpsbasis]

The BDT Code Completion document, found in the BASIS documentation at https://documentation.basis.cloud/BASISHelp/WebHelp/ide/BDT_Code_Completion.htm
(Development Tools > Eclipse Plug-ins > bdthelp > BDT Code Completion), provides a summary of what code completion features were provided for the Eclipse IDE, along with sample code for testing. This document is a good reference which could be used to test the code completion capability of the BBj Language Support extension for Visual Studio Code, given that it represents a minimum acceptable standard and does not attempt to match the entire code completion capability that is commonly available for other languages.

At this writing, the BBj Language Support extension, while a good and important beginning and something that EVERYBODY is counting on, is not yet capable of the things specified in this document.

@mphelpsbasis, with your in-depth knowledge of the details, can you please go ahead and test the features described there item by item and create distinct, granular issues for each detail you see that has not been implemented?
