I’m going to attempt to translate a perlin noise function (from

things that stopped me from starting.
1) What is & doing in this assignment? I see this many places in assignments.
int h = hash & 15;
That's an "and".
Please keep in mind that & is a bitwise and in C
whereas && is a logical and;
this makes much difference and has to be implemented or converted
differently
with Pascal, IMO.
the closest equivalence to bitwise and in Pascal are set intersections,
IMO.
If I had to implement that on integers using standard pascal, this would
cause me some headache ...
Kind regards
