Hi,

COMP-4 and Binary or COMP all are same. So you can move the
S9(9) COMP-4 variable to 9(04).

Correct me if I am Wrong.

Thanks

Hi Boss....

S9(9) COMP it will take 4 bytes, then 9(4) also will take 4 bytes only..

but here we are moving value of S9(9) Comp, here the length of the field S9(9) Comp is 9 ,

if we move the S9(9) to 9(4), the value will tructe....

Correct me , if i am wrong....

To complete the discussion you must code the receiving field as
PIC S9(10) to avoid truncation and preserve the sign.

hi,
i think it will not work fine bacause s9(9) comp-4 will take (9+1)=5 bytes,and if we want to move this value to 9(04) then left most value will be truncated..pls correct me if i'm wrong.

hi,
i think it will not work fine bacause s9(9) comp-4 will take (9+1)/2=5 bytes,and if we want to move this value to 9(04) then left most value will be truncated..pls correct me if i'm wrong.

Hi Jayanta,

What you described is not how the length of a COMP/COMP-4/BINARY field is determined; that's how a COMP-3 field is determined.

Do a search on COMP and/or COMP-4 for an explanation
