Moves contents of the source into the destination.
mov dest, src
To learn more about registers, see Registers.
The following code fragment shows the operations performed.
if(dest == A0)
{
    float p = (float)floor(src.x);
    *(int*)&dest.x = FloatToInteger(p);
}
else
{
    dest = src;
}
// This example outputs a constant diffuse color. vs.1.0 m4x4 oPos, v0, c0 ; transform vertices by view/projection matrix mov oD0, c4 ; output constant color // The resultant vertex color is green and is shown below.
 
// Additional code initializes the constant register c4 with the color green.
D3DXMATRIX mat, matView, matProj;
D3DXMatrixMultiply(&mat, &matView, &matProj);
D3DXMatrixTranspose(&mat, &mat);
// set C0 with the view and projection matrix
m_pd3dDevice->SetVertexShaderConstant(0, &mat, 4);
// set register c4
float color[4] = {0, 1, 0, 0};
m_pd3dDevice->SetVertexShaderConstant(4, &color, 1);
// The first SetVertexShaderConstant method binds the C0 register 
// with the first row of the view/projection matrix (rows 2, 3 and 4 are 
// bound to registers C2, C3 and c4 also). The m4x4 instruction (in the 
// shader file) loads the data.
// The second SetVertexShaderConstant method binds the C4 register 
// with the color green.
