Bad data in as/400 database.. cant display record

ToddN2000 — Fri, 04 Sep 2009 17:58:20 +0000

We have a user that insists on using cut and paste to enter data into our system. The problem is bad hex/ascii chars are causing errors trying to retrieve the data.

If you try to edit the data using STRDFU it gives the message “The retrieved record contains invalid data.” To make things worse you cannot F-23 the record to delete it.

The only way we have found to fix our file is copy from RRN 1 to just before the bad record to a temporary file. Then we copy to just after the bad recoed to the end of file to the temp with the *add option. We then copy the temp file to our production file *replace. To complicate things this has to be done off hours and the file is used constantly. This means that customer is dead in the water until the next day.

Is there a way to edit the database file in a hex format?

Some of the bad chars they are using are elipse( a single char size …), tab and carriage return characters to name a few.

Any help is greatly appreciated.

Does anyone have any suggestions as far as reference material that would help me understand EBCDIC Character sets, Hex, Binary, and how you can tie them into CL’s & RPGLE’s, and whatnot?

Over and under Hex display/edit

Hi,

I’m busy with a utility program on the i-Series (written in OPM RPG – which is still the standard where I am) and I need to be able to show some fields in hex mode for editing, like the DSPPFM command when you press F10 and F11. So I’m looking to display the hex values “over and under”, with the first hex digit on one line and the second hex digit on the line underneath. My question is : Is there an easy or neat way to do this, or do I have to translate everything from/to hex myself?

Thanks in advance,

Martin Gilbert.
