[fpc-devel] Some thoughts on multi-line string support, and a possible syntax that I think is perfectly clean and Pascal-ish.

Do you mean this? I still get an error without H+.

{$mode objfpc}

program test;

var lines: ansistring = `
  #version 150

  uniform sampler2D textures[8];
  in vec2 vertexTexCoord;
  in vec4 vertexColor;
  in float vertexUVMap;
  out vec4 fragColor;

  void main()
  {
    if (vertexUVMap == 255) {
      fragColor = vertexColor;
    } else {
      fragColor = texture(textures[int(vertexUVMap)], vertexTexCoord.st);
      if (vertexColor.a < fragColor.a) {
        fragColor.a = vertexColor.a;
      }
    }
  }`;

I do not believe that this behaviour is related to any code I've added so far, however, as I don't see how it possibly could be. Seems like a bug that nobody came across before.

Then it’s a bug I guess? That would be nice to fix because it will be a problem for exiting code if we’re forced to turn on H+ for the entire unit. It’s probably not related to your code I agree. If anyone know if this is a bug/can be fixed please let me know.
