Re: Date conversion to Julian - RPG IV rookie..

What helped me to figure it out is this statement:  "A date field always
knows what it is,  you never have to tell it".

Thanks Rick (and Scott).
 
DUH!  Reading (for the 12th time) from the RPG IV programmers reference:
 
"The second parameter is the date format for character or numeric input.
Regardless
of the input format, the output is returned in *ISO format."
 
Note the word INPUT, not output, so even the RTFM approach got past
these old eyes....
 
Thanks for re-stating the obvious for me (Hey! You'd make great
consultants......!)
