Need help optimizing this piece of code

[Structure]

I will probably use the same technic I used in another part of my program where once the object (structure) is assigned I don't free it and just use a pointer to move to the next or previous object and create a new one only when neccessary. I will have to add a tgrid *next in my structure in order for this technic to work. I will free the whole grid only at exit time.
