REM to launch the ANTLR SDK Tool: GRUN. Grun is a trivial client of the Antlr4 API,
REM it just parses a source. It can output the AST in text mode, with -ast switch.
REM or, like in this batch, a window with a graph visualizer with the -gui switch.
REM This helps when working with the grammar file azslParser.g4 to see what happens
REM to the parse tree.
