I know the difference between a comp and and comp-3 variable. Could some1 please tell me in what all scenarios the usage comp and comp-3 is preferred?

All? That would take some time. I could devote an hour of my day to you, or ...

Have you done any research yourself - I'm just guessing this is a topic that others have already written about, either here or elsewhere (read "world wide web") dontcha think?[/i]

You should consult with some of your more Senior Tech's at your site. I'm sure they can give you some sound answers, which you need to run with.

As far as your request, you need to spend time researching this on your own, because an extensive explanation (as Phil has said) is time consuming and is above and beyond what members provide (and for free).

Remember, we are a Help board and members need to put in an effort in an attempt to resolve their questions before posting. If you do this and provide your findings in a given post, you'll find that other members are more receptive and more willing to lend a hand.

Thank You,

Bill

From my research: Comp variables are used as counters and should be integers. Comp-3 variables are used for numeric data like amounts and decimal points are allowed.

Your "research" is flawed.

when you use the db2 database, the data type maybe :
decimal(m,n) -----> pic s9(m-n)vn comp-3.
smallint -----> pic 9(04) comp.
integer -----> pic 9(09) comp.

however, comp-3 always used to represent amount when comp is used
for counter and address.

I'll agree to "incomplete," but suggest that incomplete ==> flawed in the context of a newby who would accept another newby's "research" as gospel.

Hi Phil,

My research shows that 3+1 = 10.

[I forgot to tell you I use base 3 arithmetic.]

Robert Sample · Posted: Thu Sep 02, 2010 11:02 pm

Uh, in base 3 wouldn't 10 represent 3?
