Answer / elite group
Comp -- binary form
Comp-3 Packed Decimal
Usages are:
Display: Default it occupies the number of bytes is equal
to the size of the data-item
Comp -- Binary Number of bytes is equal to the size of the
data-item
Comp-1 -- 4-Bytes no pic clause is required
Comp-2 -- 8-byted no pic caluse is required, Double
precision
Comp-3 -- Packed Decimal Number of bytes is
(n+1)/2 -- if n is odd
(n/2)+1 -- if n is even
Comp-4 --- Same as Comp

Answer / cauvitha
comp - used for binary representation. To make the calculations faster. it can have S and 9.
Memory usage is
s9(1)-s9(4) - 2bytes
s9(5)-s9(9) - 4bytes
s9(10)-s9(18) - 8bytes
===
comp-3 - used to store packed decimal values. Stores comparitively more values than comp. It can have S, 9, V.
Memory usage is
n/2 + 1 (Even)
n+1/2 (odd)

Answer / sultana
Usage Clause :COMP
Binary representation of data item.
PIC clause can contain S and 9 only.
S9(01) – S9(04) Half word.
S9(05) – S9(09) Full word.
S9(10) - S9(18) Double word.

What are the different types of condition in cobol and write their forms.
consider the following progrm statements MOVE 0 TO SW.NO.OF.REC PERFORM PRI-OUT UNTIL SW=1 DISPALY NO.OF.REC STOP RUN PRE-OUT READ IN-FILE AT END MOVE 1 TO SW WRITE OUO-REC FROM IN-REC ADD 1 TO NO.OF REC if the IN-FILE contains 1000 records what value will be displayedafter the PERFORM is over?assume that N0.OF.REC has PIC 9(4) a.1000 b.1001 c.1 d.none of the above since there is a syntex error
