Can X11-Basic generate stand-alone programs, which may run without the xbasic executable ?
Yes. You can create stand alone executable files with xbc the x11-basic pseudo compiler. X11-Basic does not translate its input into assembly. The compiler compresses the sourcecode and links it to the interpreter. Question: May I charge for my X11-Basic programs ? Answer: Yes, you may. But you should state clearly, that xbasic itself is available free of charge. Refer to the copyright for details.
