In analyzing the compilation of PL/I program, the term "Lexical analysis" is associated with
-
Resolution of externally defined symbols is performed by

System generation:
-
The Memory Address Register
-
In virtual memory systems, Dynamic address translation
-
Fragmentation of the file system
-
A non-relocatable program is one which
-
Which of the following are(is) Language Processor(s)
-
In which addressing mode the effective address of the operand is the contents of a register specified in the instruction and after accessing the operand, the contents of this register is incremented to point to the next item in the list?
