Interpreter for a rudimentary BASIC style scripting language.

Windows, Linux or BSD command line app created in C/C++. Other languages would be considered. Open to suggestions. Performs simulation(execution) and syntax checking of a stripped down, rudimentary dialect of BASIC. Refer to attachment outline for details. It loosely relates to the idea of an "application virtual machine". There is no UI. Intended programs will typically be short, more resembling a script. You can use lexers and parse generators such as ANTLR. Thank you.
