Answer:
The mips program will be as:
.MODEL SMALL
.STACK 100H
.DATA
PROMPT_1 DB \'Enter the time in seconds up to 65535 = $\'
PROMPT_2 DB 0DH,0AH,\'The time in hh:mm:ss format is = $\'
SEPARATOR DB \' : $\'
.CODE
MAIN PROC
MOV AX, @DATA ; initialize DS
MOV DS, AX
LEA DX, PROMPT_1 ; load and display the string PROMPT_1
MOV AH, 9
INT 21H
CALL INDEC ; call the procedure INDEC
PUSH AX ; puah AX onto the STACK
LEA DX, PROMPT_2 ; load and display the string PROMPT_2
MOV AH, 9

POP AX ; pop a value from STACK into AX
XOR DX, DX ; clear DX
MOV CX, 3600 ; set CX=3600

CMP AX, 10 ; compare AX with 10
JGE @HOURS ; jump to label @HOURS if AX>=10
PUSH AX ; push AX onto the STACK
