Sample data structures:
ds3p2 DS
f3p2 3P 2
ds4p2 DS
f4p2 4P 2
...
hdr-1 goes to logfile-fld1
Chain out to QADBIFLD for size of logfile-fld1. Let's say it is 3P2. Map
this knowledge into a field, let's call it MAP. Let's also say that
QADBIFLD says that it starts in position 20, or X.
select
where map=3p2
eval f3p2=thevalue
eval substr(string:x:2)=ds3p2
where ...

This is EDI reason.
You mean put over my flat record on record from my destination file? Sounds
good, and how to handle numeric values in my flat record? I could
concatenate hex strings and next convert to character, would it be good
solution?
By the way, and sorry for my ignorance but I always want to know who (what)
is the "Cole"? :-)
Thank You Rob

SQL would be a nice tool. Must be some alternative. Since many code
developers shy away from it for some reason or the other. That being said,
they're are packages out there designed to do this kind of processing for
EDI reasons. We use a package from Harbinger. No source code is included
however so their technique remains hidden. And the AS/400 we use it on
does not have a compiler so it's not like they generate code on the fly.
Mapping the data into a record is no big deal. This can be done with some
string manipulation and by reading the file QADBIFLD. You might have to
set up some temporary variables to help with the numerics.
Hmm, try this. Create a file with a huge record size as one field.
Declare this file in your RPG as USROPN. Compile it with level check
turned off. Use the system command to OVRDBF this file to the files
declared in your format file. I see an OVRDBF, OPEN, WRITE, CLOSE, DLTOVR
for each record in your message file. Well you might limit this by doing
control break processing based on the message format. Then you would only
have to do the OVRDBF, OPEN, CLOSE and DLTOVR on each control break.

EOM+ControlNumber
Format of message file
Tag Element Type .. Destination File Destination Field
HDR 1 Num .. LOGFILE FLD1
HDR 2 Char .. LOGFILE FLD2

I want to read the message file search for tag in format file and write
data to apropiate fields in files LOGFILE, ORDES, DETAILS

Could you paste some sample records? And a sample usage?

Hi all
I need to do some sort of data mapping
i.e.
in file 1 I have message from other system
in file 2 I have format of this message and names of files and fields where
this information should be stored in my shop (Because format of message can
be changed I would like to separate code from this format)
How to write data to files/fields given as a parameter?
Is there any way except SQL?
Any API?
Any ideas?
Thanks in advice
Marcin
