So if you use second model.
you=ent_create(cube.mdl,my.pos,null);
you.invisible=on;you.passable=on;
my.skill100=handle(you);//we here are storing extra 100 skills
//with second model who are invisible and passable

you=ptr_for_handle(my.skill100);
if(you.skill1==kautkas)//the same as 101
{daritkautko.....}

So if we use array
var array[100];
/*for example
var i=0;
while(i<array.length)
{
array[i]=i;
i+=1;
}
*/
my.skill1=array;
//and then we can use whole 100 skills from one skill
array=my.skill1;
vec_set(my.pos,vector(array[97],array[98],array[99]));
//and do what ever we want and store again
//So its your choise
