I have had proplems in the past when I READC to a SFL,
write/read/exfmt other formats to the same DSPF and then
try to update the SFL record I had read before. I have always
been able to modify my code do the update immediately
following the READC and before I do the other write/read/exfmt
to the DSPF and this has solved my problem. I could always
re-CHAIN to the SFL using the relative record number prior
to the UPDATE, I just haven't done it that way yet.
