qbjs & qb64pe compatibility and equivalent for other languages like Python?

[dbox]

I'm finally getting around to being curious about qbjs - what features of QB64PE does it not support? 

I’m maintaining a list of both supported and unsupported keywords here:
Supported Keywords
Unsupported Keywords

There is also a general outline of the QBasic language support here:
QBasic Language Support

The goal is to increase the level of compatibility with each release.  Version 2.0.2 is what I’m currently targeting from a compatibility perspective for QB64.  This was the current version when I first started tracking and the last version before the community split.
