Question $2$: $(6$ marks$)$

a$.$ Consider the three following programs. Suppose they are linked in the sequence

of PROG$2+$PROG$3+$PROG$1,$ and the beginning load address is $002054.$

HProg $100000000014E$

DALPHA $00001$FMAX $00014$B

RINF ZERO

T$0000001$C$6$D$000375012$C$05000003$A$0132$B$213$C$2$B$3000160$F$21359041$A$0153$B$2$FEA

T$00014$B$03000000$

M$00001005+$ Prog $1$

M$00014$B$06+$ INF

M$00014$B$06-$ ZERO

E$000000$

HPROG$2000000000026$

DMIN $000023$ZERO $00001$D

RALPHA MAX

HProg$3000000000023$

DINF $000020$

RMAX MIN

$........$

i$.$ Derive the ESTAB that shows the external symbols and their addresses.

ii$.$ For ONLY PROG$1.$ Show the address of the memory locations to be modified along with

their new content for all programs after the operation of linking loader
