- Correct Answer
- a program that automate the translation of assembly language into machine language
- 1. In analyzing the compilation of PL/I program, the term "Syntax analysis" is associated with
Options- A. recognition of basic syntactic constructs through reductions
- B. recognition of basic elements and creation of uniform symbols
- C. creation of more optional matrix

- B. Specify, to the operating system, the beginning and end of a job in a batch
- C. Allocate the CPU to a job
- D. All of the above Discuss
- 3. A development stategy whereby the executive control modules of a system are coded and tested first, is known as
Options- A. Bottom-up development
- B. Top-down development
- C. Left-Right development
- D. All of the above Discuss
- 4. The advantage(s) of incorporating the macro processor into pass 1 is/ are:
Options- 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 Discuss
- 5. Which of the following program is not a utility?
Options- A. Debugger
- B. Editor
- C. Spooler
- D. All of the above Discuss
- 6. A compiler for a high-level language that runs on one machine and produces code for a different machine is called
Options- A. optimizing compiler
- B. one pass compiler
- C. cross compiler
- D. multipass compiler Discuss
- 7. Assembly code data base is associated with
Options- A. a permanent table which lists all key words and special symbols of the language in symbolic form
- B. a permanent table of decision rules in the form of patterns for matching with the uniform symbol table to discover syntactic structure
- C. consists of a full or partial list or the tokens as they appear in the program. Created by Lexical analysis and used for syntax analysis and interpretation
- D. assembly language version of the program which is created by the code generation phase and is input to the assembly phase Discuss
- 8. A non-relocatable program is one which
Options- 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 Discuss
- 9. Convert the 11014B machine language instructions into assembly language, assuming that they were not generated by pseudo-ops:
Options- A. ASRA
- B. LOADA h#OD4E, i
- C. STOREA h#014B, d
- D. ADDA h#01FE, i Discuss
- 10. Terminal Table
Options- A. a permanent table which lists all key words and special symbols of the language in symbolic form
- B. a permanent table of decision rules in the form of patterns for matching with the uniform symbol table to discover syntactic structure
- C. consists of a full or partial list of the tokens as they appear in the program. Created by Lexical analysis and used for syntax analysis and interpretation
- D. contains all constants in the program Discuss
