Hi friends

It can be calculated as (No of bytes+1)/2. Now you tell me how many bytes A will occupy.

Is the declaration correct.
To my understanding we can store a maximum of length 18. ie.
01 A PIC S9(18) comp-3
which implies (18 / 2) + 1 =>10 bytes.

whereas in the post they have declared it as S9(17)V9(2). Is that correct ?

Correct if me if am wrong.

Yes Ralph! You are correct. I overlooked it. We can't declare more than 18 digit positions for comp-3 items.

Dear Friends
So overally the formula wil be like this:

S9(n)V9(m) Comp-3 Should be----((n+m)+1)/2

Is it?

Correct if it is wrong?

Thanks
Chandra

Yes chandra! But remember you can't cross 18 digits

is the 18 didgit limit only for comp-3 item ? or for all numeric items e.g can we define s9(18)v(2) ? if yes, what is the max that can be defined

hi everyone,

Can any body let me know which one is the correct formula to calculate the number of bytes used by a COMP-3 field.

1. (n+1)/2

2. (n/2+1)

plz let me know the correct one.

It's the first one

To make the calculations easy
use (n+1) / 2 for odd numbers
and for even numbers (n/2) + 1

Please correct me if I am wrong.

Hi Prasanth

The formula is like this:

FOR COMP-3 VALUES

[code] IF n IS ODD
TOTAL NO OF BYTES= (N+1)/2
ELSE
TOTAL NO OF BYTES= (N/2)+1
