Re: julian date

Mike,

If you are using ILE COBOL and date data types, you can use
a move statement or the intrinsic function
CONVERT-DATE-TIME.  Set up working storage field to contain
the DATE data type and define it as a julian date.
 Redefine the julian date so you can get at the year and
day.  Use the following:


(copied from the code/400 online manual)

>>-FUNCTION
CONVERT-DATE-TIME----------------------------------->

>----(--argument-1--argument-2--+-----------------------------+---)->
                                '-argument-3--+------------+--'
                                              '-argument-4-'

>--------------------------------------------------------------><


argument-1
Can be:
A date, time, or timestamp item
An item of class alphanumeric
A non-numeric literal
An item of class numeric integer.

argument-2
Specifies the category of the return value and must be one
of the following keywords:
DATE
TIME
TIMESTAMP.
If argument-1 is a date, time, or timestamp item,
CONVERT-DATE-TIME can only convert:

A date to a date, or a timestamp
A time to a time, or a timestamp
A timestamp to a date, a time, or a timestamp.
If argument-2 is TIMESTAMP, neither argument-3 nor
argument-4 can be specified.

If argument-1 is a date-time item, a date-time move is
done.

If argument-1 is a numeric integer, the returned date-time
item will be right-justified and truncated, if it is longer
than what is allowed by the date-time format specified in
argument-3.

If argument-1 is anything else, the returned date-time item
will be left-justified and truncated, if it is longer than
what is allowed by the date-time format specified in
argument-3.


argument-3
Specifies the format of a date or time item. It must be:
A nonnumeric literal at least 2 characters long
The keyword LOCALE
The FORMAT OF special register.
For a list of valid literals and the rules that this
argument must follow, refer to the SPECIAL-NAMES FORMAT
clause described in FORMAT Clause.

Argument-3 should represent a category that is referred to
by argument-2.

If argument-3 is the keyword LOCALE, then the format of the
date or time is based on a LOCALE. If argument-4 is not
specified, the current locale is used, otherwise the locale
associated with the mnemonic-name or the LOCALE OF special
register is used.

If argument-3 is not specified, the format of the returned
value is dependent on the SPECIAL-NAMES FORMAT clause. If
no format has been defined in the SPECIAL-NAMES paragraph,
*ISO format is used.


argument-4
Must be a mnemonic-name associated with a LOCALE, or the
LOCALE OF special register.
Argument-4 must follow these rules:

If argument-4 is specified and argument-3 is a locale-based
format literal, for example contains %p, then the
locale-based format literal would use the locale specified
in argument-4 to determine the actual value of the
conversion specifiers.
If argument-3 is a locale-based format literal (for
example, contains %p) and argument-4 is not specified, the
locale-based format literal would use the current locale to
determine the actual value of the conversion specifiers.
If argument-3 is a locale-based format literal (for
example, contains %p), and the LOCALE OF special register
is used to refer to a non-locale item, the locale-based
format literal would use the default locale to determine
the actual value of the conversion specifiers.

It takes a little playing with, but it is an easy way to
convert any date.

Hope this helps.
