Re: Problems with CEE date APIs

[booth@xxxxxxxxxxxx]

Here's what I did to get the last previous Friday to any date:

 D DateISO         s       d   DatFmt(*iso
 D DateTest        s       d   DatFmt(*iso) INZ(D'1999-01-02')
 D DateAnyDay      s       d   DatFmt(*iso)

 * Get last Friday:
 C     DateAnyDay    SubDur    DateTest      Tmp7:*D       7 0 
 C     Tmp7          Div       7             Tmp7 
 C                   mvr                     Tmp7 
 C                   Eval      Tmp7=tmp7+1 
 C     DateAnyDay    SubDur    Tmp7:*D       DateISO 
 C                   Move      DateISO       Tmp10        10

        Subject:        Problems with CEE date APIs

Hello,

I am trying to write a program to calculate the last Friday of the month.

I decided to use the CEE date APIs in a ILE RPG program.

My problem is that the CEEDAYS API will only work if I place a DSPLY
directly after it! This is obviously not desirable.

I have found this to be the case at both V3R2 and V4R4.

Can anybody see what I am doing wrong?

Many thanks

Alan

Source code follows:
