Two mistakes:

Code:

  klmix$ = rgb$( r , g , b )
should be:
  color.mix$ = rgb$( r , g , b )

and:

Code:

    #m "color" ; kl$
should be:
    #m "color " ; kl$

The beta version of LBB you have contains File... Insert and File... Compare so I suggest you replace each 'include directive with the file itself, and then compare the merged result with the working version.

Generally, I would recommend only using 'include with modules that have been thoroughly tested and are known to work. Otherwise it's too difficult to debug a program using includes.

in the begining it was 1 file
but i splitted it later
because i want to write in parts
so i dont have to write it twice or more
i want to extend this farder whit more parts
[ see 3d line cubes ]
and i can only post 10K here

in the future my files wil be bigger if i dont use include

I do not believe it. Splitting a program into multiple modules makes no difference; when you run it, it is the same program (apart from the line numbers).

I listed in an earlier post a fully working 'sphere' program split into multiple modules. If necessary go back to that:

a try at OOP Code:

new p as t3d 255 , 3 , 6
new p1 as t3d 4 , 4 , 4
print p::toStr$()
print p1::toStr$()
''next line goes also wrong whit "!" in front
''p = p::add( p1 )
print p::toStr$()
discard p 
discard p1
end
class t3d
  dim x , y , z
  sub t3d
    x = 0
    y = 0
    z = 0
  end sub
  sub t3d nx , ny , nz
    x = nx
    y = ny
    z = nz
  end sub
  function get.x
    get.x = x
  end function
  function get.y
    get.y = y
  end function  
  function get.z
    get.z = z
  end function
! function add( a as t3d ) as t3d
    new q as t3d x+a::get.x() , y+a::get.y() , z+a::get.z()
    add = q
    discard q
  end function
  function toStr$()
''this is now right
    toStr$ = "( " + str$( this::get.x() ) _
          + " , " + str$( this::get.y() ) _
          + " , " + str$( this::get.z() ) + " )"
  end function
end class

i tryed this Code:

''bluatigro 14 feb 2015
''mod-test.bas

'include t3d.bas

print "now in mod test bas"
new a as t3d 1 , 2 , 3
print a::toStr$()

Code:

''bluatigro 14 feb 2015
''t3d.bas

new p as t3d 255 , 3 , 6
new p1 as t3d 4 , 4 , 4
print p::toStr$()
print p1::toStr$()
''next line goes also wrong whit "!" in front
''p = p::add( p1 )
print p::toStr$()
discard p 
discard p1
end
class t3d
  dim a , b , c
  sub t3d
    a = 0
    b = 0
    c = 0
  end sub
  sub t3d x , y , z
    a = x
    b = y
    c = z
  end sub
  function x
    x = a
  end function
  function y
    y = b
  end function  
  function z
    z = c
  end function
! FUNCTION add( d AS t3d ) AS t3d
    new q as t3d a + d::x() , b + d::y() , c + d::z()
    add = q
    discard q
  end function
  function toStr$()
''this is now right
    toStr$ = "( " + str$( this::x() ) _
          + " , " + str$( this::y() ) _
          + " , " + str$( this::z() ) + " )"
  end function
end class

''t3d.bas

error :
- t3d.bas output corect
- mod test.bas only t3d.bas output

t3d.bas includes an END statement (and other code which must come after the main program) so, of course, anything following the 'include t3d.bas will not be executed:

Code:

    print "This is executed"     ' this is in the included file
    end                          ' this is in the included file
    print "This isn't executed"  ' this is in the base program

Sometimes I think the 'include directive has been misunderstood. It quite literally 'includes' the specified file at that point in the program; nothing 'clever' or 'magic' happens!

Presumably it's this line:

Code:

! FUNCTION add( d AS t3d ) AS t3d

That starts with an exclamation mark, so LBB will assume it is BBC BASIC code and bypass the translator, but it's not BBC BASIC code (it's not LBB code either)!

As I've said before do not put code in an included file until it is thoroughly debugged! Because neither the debugger nor the run-time error reporting can tell you in which line an error occurs - they will both simply indicate the 'include line - it makes debugging included code very difficult.

First test it 'inline' as a conventional program, and only when you are very confident the module does what you want and is completely bug-free put it in a separate file. If it does subsequently fail, despite your care, put it back 'inline' to fix the problem.
