RE: dates in /free

[rob@xxxxxxxxx]

If you're a performance dweeb then you might want to consider this:
  Which is more likely in your case:
    Valid dates
    Invalid dates

Because if the answer is Valid dates then you're better off to use the 
monitor and on-error logic.  That only get's triggered if there is an 
error.  Instead of the cycles taken by checking every date.

So, instead of this:
       Test(DE) *YMD Ymd;
       If Not %Error;
         mdy = %Int(%Char (%Date (ymd: *YMD): *MDY0) );
       Endif;

You'd have this:
       monitor;
       mdy = %Int(%Char (%Date (ymd: *YMD): *MDY0) );
       on-error 00112;
         // ... handle invalid date
       on-error;
         // ... handle other errors
       EndMon;
       Endif;

>> Also, how can I use the TEST opcode in rpgle/free to test a date in a 6
>>digit numeric field?

Building on Jon's example, you could code:

     D mdy             s              6  0
     D ymd             s              6  0 Inz(030827)

      /Free

       Test(DE) *YMD Ymd;
       If Not %Error;
         mdy = %Int(%Char (%Date (ymd: *YMD): *MDY0) );
       Endif;

 etc.
