	  Then in the foo.bas file:

	  Unit other.something.Foo
	  export my_var

	  The unit file should be saved in $UNITPATH/other/something.
	  If not defined, $UNITPATH is inferred as the host program
	  file directory.

2007-10-10
	* A runtime error is now created in lieu of crashing when you
	  pass a value less than 0 to the LEFT and RIGHT string commands.

	  call statement:

          func foo(s)

          sub bar
            ? "in bar"

          pb = @bar
          call pb
          call @bar

          is a better replacement (IMHO)

          lieu of a file name. After calling this command, the calling program
	  now successfully resumes.

VERSION 0.9.0
--------------------------------------------------------------------------------------------------------------------------------
2004-05-01: ndc
	Human language depented files for messages and keywords.
	The messages and the keywords can be easily translated to another language.
	This is not suggested because that means incompatible source-code but it is very usefull for education purposes;
	I believe that, the kids will work better if they are using their natural language
	(and we are very sensitive on that matter).
	I suggest to the "translators" to be very carefull, there is no mean on a word-to-word translation.

2003-03-10: ndc
	new c-modules: mod_gdbm, mod_mysql

2003-03-09: ndc
	fix: ptdistln, ptdistseg
	new: POLYCENT (centroid of polygon)

2003-02-24: ndc
	END IF: keyword with space is supported now

2003-01-24: ndc
	FOR-IN: if the IN parameter is not an array (probably an empty variable) the FOR jumps to
	--- the next command after 'NEXT'

	several internal changes for easy development.
	--- cxx_sb.hpp provides a new iterface to whole SB.
	--- SB can compiled as a C or C++ library. That would
	--- help a lot the IDEs developers. Main Makefile
	--- splitted, it is working like main-menu now.
	FLTK IDE added but not finished yet.
	--- Actually that shows the power of the libsbasic.

	update: compiler speedup for PalmOS 3.5+
	--- VMTs not used on 3.5+ (no actually needed)
	new code: lopen_bridge.h
	--- I rewrote the VMTs. The code was a mess. Several parts of SB
	--- uses #def blocks just to do simple tasks with open/close command-set
	--- So, I wrote a "driver" which cleans a lot of those parts by using
	--- real std-c emu of functions open/close for PalmOS and VTOS.
	update: new VMT
	--- VMTs are now basic part of the system. Because of lopen_bridge.h is
	--- easy portable too. In VMTs is stored a fake environment-variable table,
	--- VMTs are used for memory swaping, and will be used as basic-level database.
	update: PalmOS, On PalmOS 3.5+ the opt_safedraw (SDK3.5 draw functions) is
	--- used by default on 3.5+.

	--- runtime error.
	new: ebm, absolutely way cool on-line help!
	new: ebm, removed the 2 pixel window border.
	new: ebm, partial MMC file support; reading and listing files from sb code only.
	--- MMC write is not yet implemented in the operating system.
	new: ebm, updated command line editor. Entered commands are now sent directly
	--- to the interpreter. You can tap and run simple one line programs
	--- using the keyboard. Use : to separate program statements.
	new: ebm, optional SmallBASIC.ini settings control creation of .sbx files
	--- and enabling verbose compilation. settings are:
	--- genexe=0
