| Date arithmetic is not yet available in SyncSort for z/OS, unless it is an offset from the current system date. |

Hi Alissa,
Is there any way to convert the gregorian date to julian date.
Then add 7 days to julian. And then convert back this julian date to gregorian date in syncsort??
Thanks, |

Rather clear. . .
Hopefully, you have begun working on an alternative. . .
One thought might be to use date functions in db2. . . |

to disturb db2 for a simple data calculations seems a bit of overshooting
if You had searched better the forums You would have found lots of examples
using a simple cobol or even simpler a rexx script
for example to add 7 days to a variable containing a date in the format
yyyymmdd ( rexx SORTED representation ) and get the new data in the same format ...
| Code: |
olddate = yyyymmdd
tmpdate = date("B",olddate,"S") + 7
newdate = date("S",olddate,"B") |

And how about processing a huge dataset in rexx?
I got the idea that that is advised against by a lot of commenters
(to be true only a few) here.
SAS, Easytrieve e.g. could do the job too. |

I am one of them.... 
but from the ts(*) wording I got the impression that it was a dataset containing just one record
Adding an artificial db2 dependency where none is needed would be a waste of resources
precompile, bind, all the change management stuff, add as many as You want
in cobol dateofinteger(integerofdate + 7) would have achieved the same result,
even the CEE.... stuff would have achieved the same
just two lines of code
I would also add that such approach would never pass any decent quality assurance review

With all due respect, i know what a ts is. I had some difficulties with
"op" (original poster?).
But a dataset with 1 record?
I know a lot of cardlib libraries with control records
for utilities for example. But they are static files.
In my experience, if we are talking about date control cards in one record,
they were mostly in stream and changed manually by certified personnel. |

Hi Peter!
You are pretty new to the forum , You will see shortly what appalling situations we are facing here,
a "one record dataset" to keep track of something is not to be considered outrageous around here  |

Hello Enrico,
thats very true. I thought i had seen it all in my IT life,
but then I am surely mistaken. |

Stick around. . .
For some time to come yet, we (IT) are in a downward spiral.
There are more and more systems being supported by less and less able people. Many/most new people do not receive appropriate training - but it is the only training they have available.
And it is even more out of control in some of the "server environments".
I'll cease before getting on a major "roll". . .
