The Applesoft BASIC extension for VS Code has been updated to include diagnostics of chained variables. The extension will analyze workspace source files to establish chain links and use this information to give more accurate warnings against unassigned variables, undeclared arrays, or colliding names. This update also includes evaluation of literal expressions for better range checking. The Integer BASIC extension has been updated similarly. It is simplest to use the VS Code extension manager to find and install.
