I don't understand. This would read the entire file and could be a
potential huge performance issue depending upon the size of the file.

Subject: RE: Chain doesn't set %EOF
My recommendation.
SetLL(SomeKey) File;
DoU 0 = 1;
Read (File);
If %Eof(File) or
SomeKey <> KeyField;
Leave;
EndIf;
// Do something
EndDo;
Was told by IBM to never use a READE, always use a READ. From a Common
conference years ago.

Subject: Chain doesn't set %EOF
Why doesn't a failed CHAIN (which sets off %FOUND) also set on %EOF? I
can
code a read loop as:
SetLL ( SomeKey) File;
ReadE ( SomeKey ) File;
DoW Not %Eof( File );
// do something
ReadE ( SomeKey ) File;
EndDo;
Rather that doing a SetLL/ReadE combo to start the loop it used to be
shorthand to code a Chain with:
Chain ( SomeKey ) File;
DoW Not %Eof( File );
// do something
ReadE ( SomeKey ) File;
EndDo;
except Chain doesn't fiddle with %EOF so this won't work.
Could do this with RPGIII. You could put the same indicator for the
CHAIN
NotFound indicator position and ReadE EndOfFile indicator position. Any
possibility of getting Chain to set the %EOF indicator as well as the
%FOUND
indicator? Or would that break existing code?
