Yes but that is how you do it, you are handling the buffers to the DB or display, (Eval-Corr comes in very handy) you read into the input buffer, Eval-Corr to the output buffer and write(update) the record. The input buffer contains all fields that can be read (*INPUT, *BOTH) and the output buffer contains all fields that can be written (*OUTPUT, *BOTH).
ReadC display.SFITEMLIST listSflIn;
DoW Not %Eof(display);
If optionNotValid(listSflIn.Option) ;
Eval-Corr listSflOut = listSflIn;
displayInd.OptionError = *ON;
Update display.SFITEMLIST listSflOut;
Else;
// Valid Option processing
EndIf;
EndDo;

Subject: RE: READC and *INPUT datastructure
"What you want is LikeRec. The code snippets below demonstrate how to
use the 6.1 file template/local file/record DS capabilities, the last line is the ReadC operation you want to use."
That's the type of coding I'm attempting to do. I think you'll find, however, that your LIKEREC...*INPUT only brings in fields defined as input capable.
On another note, I was using external data structures rather than LIKEREC datastructures, because I thought that when you used a qualified file, that the record format were undefined. I'll have to experiment with that concept some more, maybe that would be a little better looking if it works.
