Answer
# 1		 
Working storage section:-
01 WS-VARX                    PIC X(9)   VALUE SPACES. 
01 WS-VARN  REDEFINES WS-VARX PIC 9(9).

REDEFINES: It is used to save the memory space....

ur declearing like that ws-varn will take the same memory 
of ws-varx...

when u used display statement
  DISPLAY WS-VARN
it shows the spaces... WS-VARN will take same memory of WS-
VARX irrespective of data type....

Answer

It wont show any Abend, the main purpose of REDEFINES 
clause is to use the same storage area with one or more 
data item with different sizes and PIC 's. We will face 
Abend if we try to MOVE WS-VARN TO WS-VAR.

Answer
# 5		 
I am agreed with Rookie. It will abend if any mathematical 
operation like add, subtract will be performed with 
variable WS-VARX, but if any mathematical operation is 
performed using WS-VARN then it will not abend because it 
is numeric in nature.

after redefining we can also move alphabetic to numeric or
numeric to alphabetic field . mathematical operation is 
different . if we go for that it will give s0c7.
