Re: %EOF with READC

Isn't the general rule "Read a file, write a format"?

Subject: %EOF with READC
 
I know I'm going to kick myself as soon as I hit the Send icon because
I'll see the error just a microsecond later.
 
But I cannot get the %eof() built-in function to work with subfiles. The
manual says it will (pages 479 and 710), but it doesn't like me. I have
pasted what I think are the relevant pieces of code. Hopefully someone
out there has better eyesight than I.
 
 
    FIT002FM CF E WORKSTN INFDS(WSDS)
    F SFILE(IT002B:RRN1)
 
    EXSR #Load; // Load the subfile
 
    EXFMT IT002BCTL; // Subfile control.
 
    READC IT002B; // Find the selection, if any.
    IF not %eof(IT002B);
    aaaaaa
    a 011400 Parameter IT002B is not valid for built-in function %EOF.
    %EOF is ignored.
 
  From the WDS ILE RPG Reference manual (pg 710):
 
You can specify an indicator in positions 75-76 that will be set on when
there are no more changed records in the subfile. This information can
also be obtained from the %EOF built-in function, which returns ?1? if
there are no more changed records in the subfile and ?0? otherwise.
 
Thanks.
