X11-Basic is a dialect of the BASIC programming language with graphics.
X11-Basic is a structured programming language. Structure is a form of visual and functional encapsulation in which multiple line sections of a program look and act like single units. The beginning and end of blocks are marked by descriptive keyword delimiters. Lines within blocks are generally indented to make the block visible. Most important: X11-Basic does not use line numbers.
bas2x11basic can be used to make X11-Basic template programs out of ANSI basic files. It helps converting old (real) Basic Programs with line numbers and multiple commands per line to the X11-Basic structure. Because there are so many different BASIC versions and dialects around, in most cases you will have to edit these files produced manually. But most of the work will already have been done by this converter.
For a desciption of the X11-Basic language and usage of the interpreter see xbasic(1).
bas2x11basic processes input files with extention .bas. The default output filename is b.bas.
For detailed help and description of the implemented basic commands take a look at the README file.
bas2x11basic ansibasic.bas
produces an output file b.bas
bas2x11basic ansibasic.bas -o newname.bas
produces an output file newname.bas
You can find some samples of former ANSI basic programs in /usr/share/doc/packages/X11Basic/examples.
Actually this converter is not yet complete. Further improvenents may be applied in future. Please let me know about ANSI-Basic programs which will not be converted.
If you find a bug in the ANSI Basic to X11-Basic converter, 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 kollo@users.sourceforge.net. If you have a fix, you are welcome to mail that as well! Suggestions may be mailed to the X11-Basic bug tracking system.
