Re: how to extract the most common date format

Wow thank you so much - this works great!!

How in the world would someone figure this out??

I see other users breaking apart the string into YYYY, MM, DD and putting them back together because it is not intuitive.

So one has to not only figure out that the result has to be numeric (unusual for dates in COBOL), but also one has to figure that the normal MOVE command cannot be used, rather COMPUTE must be used (as opposed to all the other DATE FUNCTIONS where MOVE is the norm).

Any idea what the reason was that a normal MOVE into an alpha field is allowed for YYYY/MM/DD but not YYYYMMDD?

Seems like a bug??

Cant be blamed on ANSI COBOL committee outside IBM because these are all IBM extensions anyways!

Thanks again!!

Sorry - I misunderstood the original intent.

There's a much easier answer than the one you derived - you should be able to just redefine the target field. It may not fit directly into what you are doing depending on how/where A0468X-DUE-DATE is defined but all you need to do is this:

01 ATR.

05 A0468X-DUE-DATE.

10 ws-num-date Pic 9(8).

and then:
compute ws-num-date
= function EXTRACT-DATE-TIME (ws-date '@Y%m%d').

A0468X-DUE-DATE is now an alpha field with the desired value.

Thanks but here is IBM doc example from "Websphere Development Studio ILE COBOL reference" v5 SC09-2539-02:

MOVE FUNCTION EXTRACT-DATE-TIME (date-2 '%m/%d') to alphanum-1.

It's a stinker - I guess I will have to format as 2012/11/28 and then SUBSTRING out the slashes.

It seems that once the slashes or spaces are gone from the edit string, the compiler chokes because it thinks it is numeric.

Is it possible that it is impossible to pull the most common date format? Does no one else use the cobol compiler with dates?

So here is the ugly code that I created:

move function EXTRACT-DATE-TIME (ws-date '@Y/%m/%d')
to ws-date-yyyy-mm-dd
string ws-date-yyyy-mm-dd (1:4)
ws-date-yyyy-mm-dd (6:2)
ws-date-yyyy-mm-dd (9:2)
delimited by size into A0468X-DUE-DATE of AFTR

Does anyone else use DATE functions in COBOL/ILE? Maybe the are full of bugs??

There are no examples on a google search.

Haven't got time to test Joel but if I recall correctly the editing should go in the target field's pic.

This works:

move function EXTRACT-DATE-TIME (ws-date '@Y %m %d')
to A0468X-DUE-DATE of AFTR

But result is "2012 11 28" (embedded spaces).

The obvious fix is

move function EXTRACT-DATE-TIME (ws-date '@Y%m%d') <--------no spaces between ymd
to A0468X-DUE-DATE of AFTR

But this gives compiler error

* 445 MSGID: LNC2780 SEVERITY: 30 SEQNBR: 027800
Message . . . . : Numeric function 'FUNCTION EXTRACT-DATE-TIME' was
found, but was not allowed in this context. Statement discarded.

Any idea how to get YYYYMMDD result?

Thanks
