I am the author of Lemick project, it is an open source Basic-like
programming language project. It has compiler from source into to
lemick VM bytecode and run-time environment with just-in-time
compiler.

In your case you would have first to compile source code, create a VM
instance and execute the code.

Lemick equivalent for the code above is the following:
      ' Test script
      Use io.console
      Dim x as Integer = 2
      Println "Hello World From my test script."
      Println "X was initialized to a value of " + x


Lemick has OOP, multitasking, packages and etc. It is written in C and
it should be not very hard to make libraries from the compiler and
run-time for embedded use. Thanks to JIT compiler it is very
efficient, times faster then any interprter. Since it is open-source
you can adopt grammar and syntax to your needs.


Hope this is helpful,
