Hi all! I am having a problem with the following shader. The compiler keeps telling:

I dont manage to see the mistake. Any help is appreciated

Shader "Custom/OceanShader" {
	Properties {
		_MainTex ("Base (RGB)", 2D) = "white" {}
	}
	SubShader
	{
		Tags { "RenderType"="Opaque" }
		LOD 200
		CGPROGRAM
		#pragma vertex vert
		#pragma fragment frag
        #include "UnityCG.cginc"
        // Uniform Variables
        sampler2D _MainTex;
        // Vertex Variables
		struct v2f {
		    float4 vertex : POSITION;
		    float2 uv0 : TEXCOORD0;
		    float2 uv1 : TEXCOORD1;
		};
		// Matrix Operator
		float3x3 m3(float4x4 m)
		{
			float3x3 result;

			result[0][0] = m[0][0];
			result[0][1] = m[0][1];
			result[0][2] = m[0][2];

			result[1][0] = m[1][0];
			result[1][1] = m[1][1];
			result[1][2] = m[1][2];

			result[2][0] = m[2][0];
			result[2][1] = m[2][1];
			result[2][2] = m[2][2];

			return result;
		}
		// Vertex Shader
		v2f vert(appdata_full v)
		{
			// Return value
			v2f output;
			// Set the texture coordinates
			output.uv0 = v.vertex.xy;
			output.uv1 = mul (UNITY_MATRIX_MVP, v.vertex);
			// Set the position value
			output.vertex = mul (UNITY_MATRIX_MVP, v.vertex);
			// Return value for the fragment shader
			return output;
		}
		// Fragment Shader
		float4 frag(v2f i) : COLOR
		{
			return float4(0,0,0,1);
		}
		ENDCG
	}
	FallBack "Diffuse"
}

Nvm I solved it. The problem was the lack of “Pass{}” keywords
