Re: how to extract the most common date format-YYYYMMDD

I'm using it like this:

WORKING-STORAGE SECTION.
...
01 WS-FELDER.
...
05 WS-AKT-DATUM PIC 9(8).
05 WS-AKT-DATUM-X PIC X(10).
...
01 ZW-FELDER.
05 ZW-DATE FORMAT DATE IS '@Y%m%d'.


PROCEDURE DIVISION.
...

AKTDATUM-ERMITTELN.
*** Current Date
MOVE FUNCTION CURRENT-DATE(1:8) TO ZW-DATE
* Extract Date to Numerical Format yyyymmdd
COMPUTE WS-AKT-DATUM =
FUNCTION EXTRACT-DATE-TIME (ZW-DATE '@Y%m%d')
* Extract Date to String Format dd.mm.yyyy
MOVE FUNCTION EXTRACT-DATE-TIME (ZW-DATE '%d.%m.@Y')
TO WS-AKT-DATUM-X

Predmet: Re: [COBOL400-L] how to extract the most common date format - YYYYMMDD

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
