Calculating Object code - SIC/XE

Question

0000    SUM         START       0       
0000    FIRST       LDX         #0              050000
0003    LOOP        LDA         #100            010064
0006               +LDB         #TABLE2         69101790

How would I calculate the object code of

0003    LOOP        LDA         #100            010064(object code)

How do I obtain the result of 010064(object code)? I already know how to do the first part(010), but I am unsure how I am supposed to get the second part of 064.

Any help would be great!

Answer 1

Since it is immediate addressing in the displacement(12bits), the immediate value needs to be represented in hexadecimal form. Therefore

LDA #100 010_ _ _

064 is written in the blank space, as it is the hexadecimal form of the displacement(100).
