X11-Basic is a dialect of the BASIC programming language with graphics capability.
ybasic is a wrapper which compiles the given X11-Basic program <filename> to bytecode and then excecutes the X11-Basic interpreter xbasic.
The basic command-files (programs) usually have the extension .bas or .xbas.
Further options will be passed to the X11-Basic interpreter xbasic as they are.
This little trick allows to run the BASIC programs as fast, as if they where compiled to bytecode before. With a little overhead of compile time at the beginning. The advantage is that you can keep the flexibility of editing the programs as if they where normal interpreted scripts.
For detailed help and description of the implemented basic commands take a look at the README file which comes with the X11-Basic package. There is also a full users manual available as *.pdf file on the homepage.
ybasic testme.bas ybasic runfast.bas -f file.dat
in the first command line can be excecuted directly.
For a complete language reference of X11-Basic please refer to the manual. You should be able to find one at http://x11-basic.sourceforge.net/x11basic.html
If you find a bug in the X11-Basic interpreter, you should report it. But first, you should make sure that it really is a bug, and that it appears in the latest version of the X11-Basic package that you have.
Once you have determined that a bug actually exists, mail a bug report to email@example.com. If you have a fix, you are welcome to mail that as well! Suggestions may be mailed to the X11-Basic mailing list on www.sourceforge.net/projects/x11-basic or posted to the bug tracking system.
