Language Processors – Section 1

1. Which of the following functions is/ are performed by the loader?

A. Allocate space in memory for the programs and resolve symbolic references between object decks
B. Physically place the machine instructions and data into memory
C. Adjust all address dependent locations, such as address constants, to correspond to the allocated space
D. All of the above

Correct Answer:  D. All of the above

2. Convert the 11014B machine language instructions into assembly language, assuming that they were not generated by pseudo-ops:

A. ASRA
B. LOADA h#OD4E, i
C. STOREA h#014B, d
D. ADDA h#01FE, i

Correct Answer:  C. STOREA h#014B, d

3. The advantage(s) of incorporating the macro processor into pass 1 is/ are:

A. many functions do not have to be implemented twice
B. Functions are combined and it is not necessary to create intermediate files as output from the macro processor and input to the assembler
C. more flexibility is available to the programmer in which he/she may use all the features of the assembler in conjunction with macros
D. All of the above

Correct Answer:  D. All of the above

4. In which addressing mode, the effective address of the operand is generated by adding a constant value to the contents of register?

A. absolute mode
B. indirect mode
C. immediate mode
D. index mode

Correct Answer:  D. index mode

5. A self-relocating program is one which

A. cannot be made to execute in any area of storage other than the one designated for it at the time of its coding or translation
B. consists of a program and relevant information for its relocation
C. can itself perform the relocation of its address-sensitive portions
D. All of the above

Correct Answer:  C. can itself perform the relocation of its address-sensitive portions
