In a input file i have 2 fields as such
roll no. status
01 y
01
01 N
02 N
02 N
03
03
03
04 Y
04 Y
04 N

Now in the output file i need to print roll no and status only once for each roll no and the status should be 'Y' if any one of the particular roll no. has 'Y' else it should print 'N'
Ex - The ouput should be
roll no. status
01 Y
02 N
03 N
04 Y
as roll no. 1 has atleast one status as 'Y" so its output status should be 'Y'
roll no 2 has no status as 'Y' so its output status should be 'N'
Similarly as roll no. 3 has no status as 'Y' so its output should be 'N'
and as roll no. 4 has atleast one status as 'Y' so its output status should be 'Y'

So can u sugest some solution

It's hard to focus when the topic title is "Focus".

Why not use a more descriptive title?

You file has to be pre-sorted by Roll No.

Then you can code something like this:

FILEDEF TEMP2 DISK C:\IBI\APPS\TEMP\TEMP2.FTM

DEFINE FILE TEMP2
FINAL_STATUS/A1 = 
IF STATUS EQ 'Y' THEN 'Y' ELSE
IF ROLL_NO EQ LAST ROLL_NO AND STATUS IN (' ','N') AND FINAL_STATUS NE 'Y' THEN 'N' ELSE 
IF ROLL_NO NE LAST ROLL_NO AND STATUS IN (' ','N') THEN 'N' ELSE FINAL_STATUS ; 
END
 
TABLE FILE TEMP2
SUM
FINAL_STATUS
BY ROLL_NO
END

Wasn't this question posted in an earlier thread?

focus

manash, posting the same question multiple times isn't going to get you more answers, it's just going to frustrate those that are trying to help.

P.S. You need a subject more descriptive than "Focus", too. Like "Focus condensing output".

Hi manash,

Can you please try the following code:

FILEDEF MYFILE DISK C:\IBI\APPS\DIALOGUE_MANAGER\MYFILE.TXT
-RUN
TABLE FILE MYFILE
PRINT 
STATUS
COMPUTE
NEWSTAT1/I1=IF LAST ROLLNUM NE ROLLNUM THEN 1 ELSE 0;
GOODSTAT/A1=IF NEWSTAT1 EQ 1 AND STATUS EQ 'Y' THEN 'Y' ELSE 'N';
WHERE TOTAL NEWSTAT1 EQ 1
BY ROLLNUM
END

The data:
myfile.txt
01 Y
01
01 N
02 N
02 N
03
03
03
04 Y
04 Y
04 N

Hope this helps.

Cheers,

Kerry

xx/a1 =
if ((rollno eq last rollno) and (last status
eq 'y') then 'y' else
if ((rollno eq last rollno) and (status
eq 'y')) then 'y' else
if (rollno eq last rollno) then 'n';

you can make this more nested, but i elongated to make it more legible. Hope it helps...
