i use glOrtho. I produce already the traditional zoom
glOrtho(-Fscaler, Fscaler, -Fscaler/ClientWidth*ClientHeight, Fscaler/ClientWidth*ClientHeight, -Fscaler, 10);
but I would like zoom on the mouse cursor.
where I zoom with my cursor, I does not want that its becomes the center of the screen.
I wants that where I zoom that remain its place
I hope to have been clearly.
I don't know if that works, but starting from what you're doing, here is how I would have done it:
glOrtho (mouse_x-Fscaler, mouse_x+Fscaler, mouse_y -Fscaler/ClientWidth*ClientHeight, mouse_x+Fscaler/ClientWidth*ClientHeight, -Fscaler, 10);
However, I'm not really sure about the result...

glOrtho (-(FMousePos.x-512)-Fscaler, (FMousePos.x-512)+Fscaler, -(FMousePos.y-350) -Fscaler/ClientWidth*ClientHeight,(FMousePos.y-350)+Fscaler/ClientWidth*ClientHeight, -Fscaler, 10);
