Hi,

I am new to Ezytrieve programming. I want to know how to define a variable with decimal point in Ezytrieve?. I want to use this field for computations involving decimal values so that my report shows output like 5456.56 etc. I have looked into manuals and found this :-
Code:

       Field-name Location Attributes
DEFINE FIELDA       100        5 A

Appreciate your help!..

From my Easytrieve notes made a few years ago (and, presumably, taken from the manual)
Code:

* attributes (l dt d) - l - length in bytes           
*
*                      dt - datatype - A - alphanumeric,
                                       P - packed decimal, 
                                       N - zoned decimal
*
*                       d - number of decimals                                             
*

Hello,

You need to get a copy of the documentation. There are quite a few things that are not difficult but they are surely not intuitive.

If your organization is licensed to use Easytrieve, all of the manuals are downloadable free fro CA Support.

In your documentation locate references to MASK.

From the documentation, understand that a MASK is only applied when a field is PRINTed or DISPLAYed.

Yes, Bill.. I searched in the forum and MASK is only applied if the field is PRINTed or DISPLAYed.

But my requirement is like this: In my input file there are about 5 fields which are defined with S9(7)V99 COMP-3. I need to subtract sum of these 5 fields from the field defined with S9(9) COMP-3 which is also defined in the same input file. When I subtract I am not getting correct result. Please help me out.

I have defined those 5 fields and WS field for computation as below
Code:

FILE INPFILE
     I-CREDIT-LIMIT   1   5  P
     I-AMOUNT1        10  5  P
     I-AMOUNT2        15  5  P
     I-AMOUNT3        06  5  P
     I-AMOUNT4        06  5  P
     I-AMOUNT5        21  5  P

WS-BALALNCE-AMT   W   10  N  2


Suppose if I-CREDIT-LIMIT = 500 and sum of other 5 fields is 465.65 then WS-BALANCE-AMT = I-CREDIT-LIMIT - (Sum of 5 fields) should give 34.35 but I am getting 46065. This is because 500 is being subtracted from 46565 and giving 46065 because I-CREDIT-LIMIT is not defined with decimal point. Can anyone guide me how can I solve this?

if you follow the P with a number, does that not indicate decimal positions?

you are not into testing/experimenting are you?

As dbz indicates, you have defined all your fields without decimal places. That is like multiplying them by 100. Here your problem.

Put a number after the P indicating the number of decimal places you have. Note that if you have a whole number, and you want it signed, you have to specify 0 decimal places. In Easytrieve Plus, the number of decimals also inidates a signed field.

dbz,
Ofcourse I am doing trial and error method to find the solution.

All amount fields are actually defined with S9(7)V99 COMP-3 and credit limit as S9(9) COMP-3. So as per your suggestions I have modified the definition as below. When I put display for amount fields it is not considering digits after decimal point.
Code:

FILE INPFILE
     I-CREDIT-LIMIT   1   5  P  0
     I-AMOUNT1        10  5  P  2
     I-AMOUNT2        15  5  P  2
     I-AMOUNT3        20  5  P  2
     I-AMOUNT4        25  5  P  2
     I-AMOUNT5        30  5  P  2

WS-BALALNCE-AMT   W   10  N  2

So its taking only 465 and subtracting from 500 giving result as 35 without decimal points.

why not change
Code:
I-CREDIT-LIMIT   1   5  P  0

to
Code:
I-CREDIT-LIMIT   1   7  P  2

?

dbz,

I-CREDIT-LIMIT is input field and is defined with S9(9) COMP-3. How can you change its definition?.

opps, I overlooked that part.

why not move credit limit to your ws-balance-amt
then subtract the others?

ws-balance-amt = credit-amt - (amt1 + amt2 ...)

i do not know of any programming or scripting language,
that will ignore decimal positions when the result of the computation had declared decimal positions.

are you subtracting everything from credit amount and then
moving to ws-balance-amt.

it would be helpful to see your arithmetic statements
in addition to the data descriptions that you have already provided.

dbz,

I am storing sum of all the amounts in one more variable and then subtracting this from credit-amount and storing the result in WS-BALANCE amout as below:
Code:

WS-SUM-AMT        W   10  N  2
WS-BALALNCE-AMT   W   10  N  2


Other information which you have requested:-
Code:

FILE MATCHFL                                     
     MATCH-RECORD                1   80  A       
     MATCH-BALANCE-AMT           1   10  N  2   


Code:

                                                 
IF MATCHED                                         
   WS-SUM-AMT = I-AMOUNT1  +                       
              + I-AMOUNT2  +                       
              + I-AMOUNT3  +                       
              + I-AMOUNT4  +                       
              + I-AMOUNT5                         
   WS-BALANCE-AMT = (I-CREDIT-LIMIT - WS-SUM-AMT) 
   PUT MATCHFL                                     
END-IF

Can you do DISPLAY HEX <field-name> for each of your I- fields and post the results/

I notice you haven't put anything in the field on MATCHFL.

Hi Chetan,

Display working storage variables in spool area and then copy spool data in the dataset after execution of job.

DISPLAY WS-SUM-AMT WS-BALANCE-AMT

In spool you will be able to view the values in deciamal format. It will surely work. Some days back I had same requirement and I did in the same way.


Thanks,

That's all fine, sandip_mainframe, but pointless. If it worked in that particular program the topic would never have been started.

Until we've seen the code/data which is wrong, there's not much we can do. Inane little bits of code are no help at all, I'm sorry to say.
