Did I miss something? Why wouldn't you use SUBDUR in RPG IV to calculate the number of days between two dates? The question always get is how to do exactly what you've already done; calculate 50 years, 11 months, 30 days. Which you can't do natively in RPG IV, directly. -Bob Cozzi www.RPGxTools.com RPG xTools - Enjoy programming again. -----Original Message----- From: mi400-bounces+cozzi=rpgiv.com@xxxxxxxxxxxx [mailto:mi400-bounces+cozzi=rpgiv.com@xxxxxxxxxxxx] On Behalf Of Beppe Costa Sent: Monday, October 17, 2005 3:39 AM To: MI Programming on the AS400 / iSeries Subject: Re: [MI400] Compute Date Duration For those who are interested to explore the MI builtin _CDD, the code follows. It returns a duration in the format 8,0 Pack. In this case the returned value is 00501130 (that is 50 years + 11 month + 30 days). Than, how can I convert this figure to a number of days ? I've also tried to use CVTD but always unsuccesfully. =========== h dftactgrp(*no) actgrp('QILE') d DateFrom s 10 inz('1954-12-03') d DateTo s 10 inz('2005-12-02') d Duration s 8P 0 d CDD PR ExtProc('_CDD') d DateDuration * value d Date1 * value d Date2 * value d InstTemplate * value d TemplateT1 ds d TemplateSize 10I 0 inz(%len(TemplateT1)) d DDAT_1 5I 0 inz(1) d DDAT_2 5I 0 inz(2) d DDAT_3 5I 0 inz(2) d Reserved1_2 2 inz(*allx'00') d Length_2 5I 0 inz(10) d Length_3 5I 0 inz(10) d Reserved3_26 26 inz(*allx'00') d*---- DDAT list --- d DDAT_Size 10I 0 inz(198) d Num_DDATs 5I 0 inz(2) d Reserved4_10 10 inz(*allx'00') d D1_Offset 10I 0 inz(24) d D2_Offset 10I 0 inz(140) d*---- DDAT_1 ------ d D1_lenght 5I 0 inz(116) d D1_format 5I 0 inz(x'0014') d D1_datseptype 1 inz(x'00') d D1_timseptype 1 inz(x'00') d D1_hourzone 5I 0 inz(0) d D1_minzone 5I 0 inz(0) d D1_monthdef 5I 0 inz(0) d D1_yeardef 5I 0 inz(0) d D1_curcent 10I 0 inz(0) d D1_centdiv 10I 0 inz(0) d D1_caltoff 10I 0 inz(0) d D1_resvd1_6 6 inz(*allx'00') d D1_eratableN 5I 0 inz(0) d D1_eratable 48 inz(*allx'00') d D1_caltableN 5I 0 inz(0) d D1_caltable1n 16 inz(*allx'00') d D1_caltable2 16 inz(*allx'00') d*---- DDAT_2 ------ d D2_lenght 5I 0 inz(116) d D2_format 5I 0 inz(x'0003') d*-D2_separator 2 d D2_datseptype 1 inz(x'00') d D2_timseptype 1 inz(x'00') d*-D2_timezone 4 d D2_hourzone 5I 0 inz(0) d D2_minzone 5I 0 inz(0) d*-D2_duratdef 4 d D2_monthdef 5I 0 inz(0) d D2_yeardef 5I 0 inz(0) d*-D2_century 8 d D2_curcent 10I 0 inz(0) d D2_centdiv 10I 0 inz(0) d D2_caltoff 10I 0 inz(82) d D2_resvd1_6 6 inz(*allx'00') d*-D2_eratb 50 inz(*allx'00') d D2_eratbNum 5I 0 inz(1) d D2_eratbOrig 10I 0 inz(1721424) d D2_eratbName 32 inz('AD') d D2_eratbRsvd 12 inz(*allx'00') d*-D2_caltable 34 inz(*allx'00') d D2_caltbNum 5I 0 inz(2) d D2_caltb1Date 10I 0 inz(1721424) d D2_caltb1Type 5I 0 inz(x'0001') d D2_caltb1Rsvd 10 inz(*allx'00') d D2_caltb2Date 10I 0 inz(5373485) d D2_caltb2Type 5I 0 inz(x'0000') d D2_caltb2Rsvd 10 inz(*allx'00') /free CDD (%addr(duration): %addr(DateTo): %addr(DateFrom): %addr(TemplateT1)); *inlr = *on; /end-free ----- Original Message ----- From: "Dave McKenzie" <davemck@xxxxxxxxxxxxx> To: "MI Programming on the AS400 / iSeries" <mi400@xxxxxxxxxxxx> Sent: Friday, October 14, 2005 6:27 PM Subject: Re: [MI400] Compute Date Duration > Beppe, > > In the CDD documentation it says "The DDAT for operand 1 must be valid > for a date duration." > > In the list of format codes it lists "Date duration" (x14) as separate > from the "Labeled durations" (x0D - x13). > > Maybe that means that the only valid format code for operand 1 is x14. > > In any case, I don't know exactly what a "labeled duration" is. > > --Dave > > Beppe Costa wrote: > > I've tried to call CDD from RPG as ExtProc('_CDD') and from MI. > > > > When the DDAT 1 is of type x'0014' I pass a pointer to a packed 8,0 and CDD > > returns correct data (number of years+number of month+number of days). > > > > When the DDAT 1 is of type x'000F' I pass a pointer to a packed 15,0 and it > > fails.
