Here is the problem, I am working with SMF records which are VSAM records. They come with FOCUS. The field in the SMFFIX MASTER
has these attibutes FIELD=SMFOFDTE,,P9 ,P4 ,$ DATE, PACKED (0CYYDDDF)

The following DEFINEs:
PDATE/P9=SMFOFDTE;
IDATE/I9=PDATE;
ODATE/I8YYMD=DTYMD(IDATE, ODATE);
SMFDATE/MDYY=ODATE;

Results:
SMFOFMSO USER SMFOFDTE PDATE IDATE ODATE SMFDATE
EDA77TW1 actrrc1 113245 113245 113245 2210/01/20 01/20/2210
113245 113245 113245 2210/01/20 01/20/2210
113247 113247 113247 2210/01/22 01/22/2210
113247 113247 113247 2210/01/22 01/22/2210

I have not worked with packed date fields in a very long time. What am I missing?

Thanks in advance - Rhonda

Hi Rhonda,
If I recall, packed date columns correleate to:
 
Byte 1:    Converts to a century 0=19, 1=20
Bytes 2-3: YY
Bytes 4-6: Day of the Year(Julian)


May need to use JULDAT/GREGDT functions...

Your code looks OK, though you could probably skip a couple of steps, but is the clue in the comment at the end of the metadata line, "0CYYDDDF"? Is it possible that the field does not contain a conventional date?

I don't know what the "F" stands for, but looking at "113245" - does the 11 mean 2011, is the 324 a component of a Julian date? 

SMFOFMSO USER    SMFOFDTE PDATE  IDATE  ODATE      SMFDATE

Tom is almost right. From the IBM info center:
Definition of the format used to represent dates (OCYYDDD+)
The numbers are written in +ve byte packed decimal.
'0C' is the number of centuries since 1900. All dates in the 21st century have '01'.
'YY' is the year.
'DDD' is the day of the year. The first day of the year is '1' and the last day of the year '366'.
'+' is hard coded as 0xC.
So:
10 January 2007  = 0107010C
 1 January 2001  = 0101001C
31 December 2012 = 0112366C

Thank you for all for your help! Here are the defines I created I may have taken more steps than necessary to get what I wanted but it was worth it. Thanks again!
*************************
PDATE/P6=SMFOFDTE;
IDATE/I6=PDATE;
ZDATE/A5=EDIT(IDATE,'$99999');
XDATE/I5=EDIT(ZDATE);
GREG_DATE/I8 = GREGDT(XDATE,'I8');
