Can't compile a shader (0:1(1): error: syntax error, unexpected NEW_IDENTIFIER)

0:1(1): error: syntax error, unexpected NEW_IDENTIFIER

precision highp float;
attribute vec3 Vpos;
varying highp vec2 vert;

void main()
{
vert = Vpos.xy;
gl_Position = vec4(Vpos.xy, 0.0, 1.0);

function goes like ALOG("$"+VertexShaderData);
