.asciiz A directive that stores a NUL terminated string in the data segment. Ok, but how is a string represented? .data STR: .asciiz "abcdefghijklmnopqrstuvxyz" .text .globl main main: la $t0, STR lw $t1, 0($t0) lb $t2, 0($t0) lb $t3, 1($t0) lb $t4, 2($t0) lb $t5, 3($t0) string.s jr $ra Each character in the alphabet is assigned a 2 digit hexadecimal number.
