following: 1. P, followed by nothing. This command causes it to print the contents of latt, using print_lattice. matrix z, of latt. For example: - consider the command W;1234. The char '; ' corresponds to coordinate (3,2,1). So this command shall write 1234 to latt.c1.c2.c3. - consider the command w 42. The char' ' corresponds to coordinate (,,). So this command shall write 42 to latt. .c.c. - consider the command WX4444. The char ' X ' corresponds to coordinate (,2,3). So this command shall write 4444 to latt.c3.c2.c0. Notes - We can verify the correspondence between printable character and coordinates by noting that: coords_to_printable (3,2,1) ';' coords_to_printable (0,0,0) ' coords_to_printable (,2,3) ' and (3) lattice
