Subfile - need to read w/in subfile display loop

Last problem is that I display a confirmation screen, for the deletes.

They want to be able to take an acct, and add to this confirmation
screen, other records (that were not selected w/ a delete number (4))

and add these to the confirmation screen. My idea is to go and read a
diff. logical that is keyed by acct, and add such records to the subfile,
just prior to the EXFMT.

But whenever I try to read this logical, the program hangs.

THe code for the display part:
C                   when      option = delete
C                   eval      rrn2 = rrn2 +1
C                   write     sfl2
C                   eval      *in74 = *on
C                   update    sfl1
C                   eval      *in74 = *off

C                   endsl
C                   readc     sfl1
C                enddo

C                   if        rrn2 > 0
C                   eval      lstrrn2 = rrn2
C                   eval      rrn2 = 1
C                   write     fkey2
C                   exfmt     sf2ctl
C                   if        (cfkey <> exit) and (cfkey <> cancel)
C                   exsr      dltrcd
C     asnkey        setll     mllc1wpk
C                   exsr      clrsf1
C                   exsr      sflbld
C                   endif
C                   endif
C

Where in this code that I put in a simple READE of the logical, the
program hangs.

I am not sure what the issue is.

Please help if you can,
Thanks,
