I have two ASCII strings and I am trying to convert them into a bit string in MIPS QtSpim. Converting the ASCII strings into bit string are already done in one of the subprograms called Binary. However, I need help with printing the bit strings that are generated in the Binary subprogram. Here are the ASCII strings:

HELLO WORLD#!3 (str1 in the code)

CRLEO93 (str2 in the code)

.data

wrd1: .word 0

wrd2: word 0

main:

la $a0, str1 # Load and print string asking for string li $v0, 4 syscall

li $v0, 8 # take in input

la $a0, str2 jal Binary sw $v0, wrd1

la $a0, str4

jal Binary

sw $v0, wrd2

Binary:

# $a0 parameter contains string

# $v0 used for the BinarySet

# $t0 used to hold nextChar in the string

# $t3 used to hold the mask for the str[j] character

li $v0, 0 # BinarySet is set as empty set

outer: lb $t0, 0($a0)

beq $t0, 0, end_outer #end of string

inner: blt $t0, 97, end_inner # a value is 97

bgt $t0, 122, end_inner # 'z' is 122

addi $t0, $t0, -32 # capitalize ASCII character

end_inner:

inner2: blt $t0, 65, end_if_2 # 'A' is 65

bgt $t0, 90, end_if_2 # 'Z' is 90

addi $t8, $t0, -65 # determine bit position

li $t3, 1 # Build mask

sllv $t3, $t3, $t8 # Continue to build mask

or $v0, $v0, $t3 # update BinarySet by bitwise OR

end_inner2:

addi $a0, $a0, 1 # walk-pointer to str[index+1]

j outer

end_outer:

jr $ra
