in short you can find it in "primitives.inc"
but here for you:
The shadow is a plane projection in this case on the ground.
Init Light and ShadowMatrix
while True:
clear screen/window/matrix
drawground
enable shadow projection
draw your scene in shadowcolor only
disable shadow projection
draw your scene normal with colors and textures
SwapBuffers()
wend

dim ShadowColor#(2) ' r,g,b
' optional only to rotate the box
dim xrot#,yrot#,zrot#
' enable Ligth0 and
' build ShadowMatrix
Gosub InitOpenGL
while True
glClear (GL_COLOR_BUFFER_BIT or GL_DEPTH_BUFFER_BIT)
glLoadIdentity()
glTransLatef (0,-3,-20) ' move the camerea
' draw the terain

' enable shadow projection
Gosub EnableShadow
' draw your whole scene in shadow color
' in this case simple a rotating box
glPushMatrix()
glTranslatef(0,3,0) ' move box over ground
glRotatef(xrot#,1,0,0)
glRotatef(yrot#,0,1,0)
glRotatef(zrot#,0,0,1)
glScalef(2,2,2)
' draw the box in shadow color

' disable shadow projection

' draw your whole scene again but now
' normal in any color or texture

' make it visible
