Reply with quote

Hi ,

I am using the following piece of code to extract the creation date of the dataset :

DATA ONE;
INFILE TESTGDG JFCB=JFCB;

BYTE81 = SUBSTR(JFCB,81,1) ;
CREATL = PUT(INPUT(BYTE81,PD1.),$2.) ;
BYTE82 = SUBSTR(JFCB,82,2) ;
CREAT2 = PUT(INPUT(BYTE82,IB2.),$3.) ;
CREATED = PUT(DATEJUL(INPUT(CREATL || CREAT2,5.)),MMDDYY10.);
PROC PRINT;
RUN;


The problem is
this code works fine if the dataset is created in 2006
but when I run this job on datasets created in 2007 this doesnot works

What I analysed is that its not able to extract year part correctly.
CREATL = ' -6 '

Actually I am a novice in SAS so I am not able to get why this output is coming.

Can any one help ?
Thanks,
-Kapil.

The following works for me.
DATA XX;
INFILE COMH JFCB=JFCB;
CRJULIANYR = INPUT(SUBSTR(JFCB, 81,1),PIB1.)+1900;
CRJULIANDAY = INPUT(SUBSTR(JFCB, 82,2),PIB2.);
CRDATE = DATEJUL(CRJULIANYR*1000+CRJULIANDAY);
DROP CRJULIANYR CRJULIANDAY;

Hi Alan,

I did run ur SAS and got the following output :

Obs CRJULIANYR CRJULIANDAY CRDATE

1 2007 48 17214

The final date is not getting calculated properly, where as the individual day and year part are doing well.

Thanks,
-Kapil.

One final piece of advice, since, by your own admission, you are a SAS novice.

Get really familiar with SAS dates, times, and datetimes. These are all numeric values and therefore, without formatting, may look unusual. However, once you learn how to display them and understand how to use the SAS functions for working with them, you will come to appreciate their simplicity and utility.
