4. Show the completed symbol table for this assembly language program. The entries should be the correct order. .ORIG x3000 LD R2, LOWER ; Load -A LD R3, ASCII ; Load ASCII difference LD R4, UPPER ; Load -Z AGAIN TRAP x23 ; Request keyboard input ADD R1, R2, R0 BRn EXIT ADD R1, R4, R0 BRp EXIT ADD R0, R0, R3 ; Change to lowercase TRAP x21 ; Output to monitor BRnzp AGAIN ; ... and do it again!! EXIT TRAP x25 ; Halt LOWER .FILL xFFBF ; FFBF = -A UPPER .FILL xFFA6 ; FFA6 = -Z ASCII .FILL x0020

Step 1

First, we need to identify the labels and their corresponding memory addresses in the program. Here are the labels and their addresses: - ORIG x3000: This sets the starting address of the program to x3000. - AGAIN: x3007 - EXIT: x300B - LONER: x300C - UPPER: Show more…
