I found this example in the DarkBASIC help files. It explains how to use the append object correctly.

rem DARK BASIC EXAMPLE PROGRAM 3
rem ===============================================
rem This program adds to and amends your model data
rem -----------------------------------------------
rem Load your object
load object "idle.x",1
rem Add walk animation data to your object appending to frame 100
append object "walk.x",1,100
rem Reset model so character faces Y angle of zero
rotate object 1,0,180,0
fix object pivot 1
rem Rotate model to face right
yrotate object 1,90
rem Set the properties of your model to wireframe and unculled
set object 1,0,1,0
rem Alternatively, an extra flag can determine texture filtering
set object 1,0,1,0,0
rem Set new speed for your model
set object speed 1,20
rem Animate your object
loop object 1
rem Set object to interpolate to a new frame at a speed of 25%
set object interpolation 1,25
rem Activate manual sync
sync on
rem Begin main loop
while mouseclick()=0
rem If walk animation required, make sure can perform animation
if animpause=0
animpause=4
if upkey()=1
if animstate=0
rem then slowly interpolate to the first walk frame
animstate=1
stop object 1
set object frame 1,105
endif
else
if animstate=1
rem else slowly interpolate to the first idle frame
animstate=0
stop object 1
set object frame 1,0
endif
endif
else
rem Count down until the interpolation has finished
animpause=animpause-1
if animpause=0
if animstate=0 then loop object 1,0,20
if animstate=1 then loop object 1,105,125
endif
endif
rem Syncronise
sync
rem End main loop
endwhile
rem End the program
end
You can find this code in Dark Basic Software\Dark Basic\help\examples\basic3d
Hope I helped.
