Consider two different control sections P1 and P2. An expression labeled VAL occurs in both programs as follows.

VAL WORD LIST1 + 5

The offset of LIST1 in P1 is 040. The load address of P1 is 4000 and the load address of P2 is 50E1. LIST1 is declared as an external definition in P1 and as an external reference in P2. VAL is at 0060 in P1 and at 007E in P2. In the notation below XX marks the byte specifying the length of the text record, which is unknown here and irrelevant.

Fill in the blanks in the text and modifier records of the partial object programs below.

H P1 H P2

D LIST1 000040 R LIST1
