I got y = ..........

I remember that I can go on a loop and insert numbers, but I don't
remember how
how do I do a simple for loop?

....in case I didn't use the right name, for (at least on basic) is some
statement that makes a loop
with a value that changes untill it gets equal to another value, and
then the loop ends

You don't. POV currently only supports #while() loops.
You can do pretty much the same thing this way:
#declare C=0;
#while(C<NUM)

    #declare C=C+1;
#end

This should be what you want.
This loop is "safe" becaue it won't go on forever, even if the value cannot
be found.

#declare C = 0;
#declare Max_Loops = 1000000000;
#declare Flag = false;
#while ( Flag=false & C<Max_Loops )

   // Insert your stuff here

   #if (One_Value=Another_Value)
      #declare Flag = true;
   #end
   #declare C = C+1;
#end

Greetings,
