Answer / nihar ranjan karan

I completely agree with Nikhil...
To add up a few more points which will be of help.....

Open up a dataset and put HEX ON , you will see the
following results assuming the variable occupies 4 bytes of
space:

low values 00000
00000

high values FFFF
FFFF

spaces 4444
0000

display item numbers FFFFFFFFFF
0123456789

characters A - Z will be of the following form:
C1-C9 will represent A-I,D1-D9 will represent J-R,E2-E9
will represent S-Z

comp-3 ...for example if number is positive 5893.
0083
059C

for negative last character will be D.

For comp it is converted into its hexadecimal equivalent.

Answer / jeena.mj

You cannot move LOW-VALUES or HIGH-VALUES to a "PIC 9"
field.

if we move low value and high values to alpha or
alphanumeric field the low value and high values are
x'0000' and x'FFFF'

Answer / nikhil

figurative constants for numeric variables.Second the first
answer gives the correct value. Please do not post anything
without confirming. Our aim is to provide correct answers.

I agree with Nikhil that our aim is to provide correct answers.

For Answer #4 (Nihar Ranjan Karan)

to compute for number of bytes for COMP-3:
count the total number of digits, divide it by 2 (disregard any fraction) then add 1. So, in the example if number is positive 5893.
it will be stored in 3 bytes only (not 4)
083
59C

---------------------------------------------

For Answer #5 (which actually a question from Prasenjit_in)

moving LOW-VALUES to a KEY-FIELD will point to 1st record while moving HIGH-VALUES to KEY-FIELD points to last record.
