In analyzing the compilation of PL/I program, the term "Lexical analysis" is associated with

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

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

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

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
