Simple Display file problem

<snip>
Hello All;
This is probably a very simple question but I am a novice RPG programmer
and
having trouble solving this. I have a display file and a RPG code
associated

I think your problem is that the record format name is the same as the
file name. If this is true, you must rename the record format to another
name using the rename keyword.

fITEM_PF      if     e             Disk  Rename(ITEMPF:RITEMPF)

Also, just a suggestion, if you are just learning RPG, consider learning
SQL from the gitgo. Do your I/O in SQL where you can.
