I tried to create a path with path_create and an entity that follow the path. var 'check' and 'node' are always 0 I write this again so you dont forget it 
var dist = 0;
ENTITY* ball = ent_create("ball.mdl", vector(0,0,20),NULL);
path_create(ball,4,4);
var check = path_setnode(ball,1, vector(0,30,20),NULL);
path_setnode(ball,2, vector(3*60,3*30,70),NULL);
path_setnode(ball,3, vector(7*60,4*30,50),NULL);
path_setnode(ball,4, vector(11*60,2*30,20),NULL);
while(1){
var node = path_spline(ball,ball.x,dist);
dist += 5*time_step;
DEBUG_VAR(check, 10);
DEBUG_VAR(node,22);
wait(1);
}

You are right. I tried it with level_load("");.
With loading an empty wmb file it works.
Why is path_create limited to 256 Nodes?

An other problem. I want to receive the name of a path (with path_set()) which i created with path_create() and use it in ent_movepath() road1.track_path is an ENTITY Pointer with an model attached to a path.
function move_car()
{
ENTITY* car = ent_create("mini.mdl",0,0);
STRING* tpath;
path_set(road1.track_path,tpath);
printf(_chr(tpath));
ent_movepath(car,tpath, 5,2);
}
printf shows me some crazy symbols an the car dont move along the path. Also a bug or my fail?

Your fail. tpath has not been initialized and hence is a vagabonding pointer. Use
STRING* tpath = str_create("#32");
// The rest of your code goes here...
ptr_remove(tpath);
instead.
Always learn from history, to be sure you make the same mistakes again...

STRING* tpath = str_create("tpath");
als0
STRING* tpath = str_create("#32"); means 32 chars of empty string.
