?? Doesn't Julian have the formst of YYDDD, so it knows when you cross year boundaries?

Note that converting to Julian in CL will not help if you expect to be
able to cross year boundaries.  You can use Julian, but you'd have to
handle the change of year and the fact that the last day of a year could
be day 365 or day 366 yourself.

The problem is that CL has no date data type.

The easiest way to do this is to do it in RPG IV instead of CL.

If you absolutely have to use CL.  Then switch to CLLE and see about
using the ILE CEE APIs, Convert Date to Lilian Format (CEEDAYS) and
Convert Lilian Date to Character Format (CEEDATE).

Convert your date to Julian, subtract the number of days, then convert
to the format you need.  Sorry, I don't have any examples.

Hi, can someone explain how to use cl to calculate dates properly?
I'm using the following;

/* RETRIEVE THE CURRENT SYSTEM DATE & TIME */ RTVSYSVAL SYSVAL(QDATE) RTNVAR(&SYSDAT) RTVSYSVAL SYSVAL(QTIME) RTNVAR(&SYSTIM) /* CONVERT THE CURRENT DATE FROM MMDDYY TO YYYYMMDD */ CVTDAT DATE(&SYSDAT) TOVAR(&SYSYYMD) FROMFMT(*MDY) + TOFMT(*YYMD) TOSEP(*NONE) /* CREATE PREVIUOS FRIDAY'S DATE BY SUBTRACTING 3 FROM CURRENT DATE */ CHGVAR VAR(&PRVDAT#) VALUE(&SYSYYMD) CHGVAR VAR(&PRVDAT#) VALUE(&PRVDAT# - 3)
CHGVAR VAR(&PRVDAT) VALUE(&PRVDAT#)
When I run the job on 0501 the pgm returns the date -3 as
20060498.  How would I have to change the code so that it
returns 0429? Any examples appreciated. Thanks
