From the manual:
Quote:

Note that DX8 vertex shaders require a small modification for running
under DirectX 9. The following declaration:
decl
{
stream 0;
float v0[3]; //position
float v3[3]; //normal
float v7[3]; //uv 1
float v8[3]; //uv 2
}
has to be replaced by a DX9 declaration:
dcl_position v0
dcl_normal v3
dcl_texcoord0 v7
dcl_texcoord1 v8
