Language Processors
Systems software is a program that directs the overall operation of the computer, facilitates its use and interacts with the users. What are the different types of this software?
assembly language version of the program which is created by the code generation phase and is input to the assembly phase
a permanent table which lists all key words and special symbols of the language in symbolic form
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
a permanent table of decision rules in the form of patterns for matching with the uniform symbol table to discover syntactic structure
to parse the source program into the basic elements or tokens of the language
to recognize the major constructs of the language and to call the appropriate action routines that will generate the intermediate form or matrix for these constructs
