how texture coords in GLSL with state/in variables (not gl_MultiTexCoord0)

    How can I get the equivalent of gl_MultiTexCoord0 using the state or in variables for GLSL?
    I tried:
    in vec4 TEXCOORD0;
    but it appears to always be zero or undefined.
    I need to move away from using the legacy/compatibility variables like gl_Vertex and gl_MultiTexCoord0 so I can write more advanced shaders than GLSL 1.2.
    I have been successful with other replacements. For example:
    in vec4 POSITION; works to replace gl_Vertex;
    param name="modelviewproj_matrix" type="mat4" state="MODELVIEW_PROJECTION_MATRIX" works to replace gl_ModelViewProjectionMatrix
    Below is patch and attached is the needed shader. I see a black cube. It should be a cube with chili peppers on it.
    On Windows, I isolated it to be only a problem with the texture coordinates. Windows supports the compatibility profile so I could do troubleshoot (Mac doesn't support compatibility profile).

      wow. forum software failure with code formatting and attaching a file.
      Attaching the JXS as a ZIP file...
