Re[2]: Built in Function ILE RPG

["Eric DeLong"<eric.delong@xxxxxxxxxxxxxxxxx>]

     I can't tell, did you get an answer to date validation? If not, 
     look at TEST(D) opcode.

Thanks   Jerry  It  works  fine. I can able to take out one more statements
out.

There is one more point I did'nt  mention.

> 1. Moving   the numerical  value ( 8, 0)  to    DATE STAMP Field with
(> Date format  *USA)

 On the above statement, by any chance if there is some invalid date like
Februry 30, then
the program is boming out with run time message.

For that , before executing the above statement, I am evaluating for
invalid date which runs almost 10+ statments.

Is there any better way for this.

Thanks again

Regards

Raj

You can do it in two instructions.
1. Move the numeric field to the date data type field. Put *USA in
factor 1, this          tells the compiler what format the numeric field
is in.
     *USA       Move       Numfield1      DateField
2. Move the date data type field to a numeric field. Put *ISO in factor
1, this tells      the compiler what format you want the result in.
     *ISO    Move       DateField      Numfield2

You could create a procedure to do this for you.
Don't use the multiply method to convert a numeric date from one format
to another.  It is very inefficient.
