Syntax error unexpected end of file at line (on d3d11)

[jBachalo]

Great resource!

One error I get after conversion is
syntax error: unexpected end of file at line...(d3d11)

However I can see nothing wrong at that specific line
pa=length(p);

I guess the problem lies elsewhere?
Perhaps the location of ENDCG or???

[smkplus]

this is a common error!

yes, sometimes it's related to the location of ENDCG like this:

            fixed4 frag (v2f i) : SV_Target
            {
                return 1;
            }
        }
        ENDCG

but usually, people forget to use the curly braces
try to uncomment line 49
