Way:1
We can execute DSPFD with *OUTFILE option, using QCMDEXC in
RPGLE program then we can read the outfile to get the name
of the file, then after we can read the file.
Way2:
Make the file to have all members available i.e.,
EXTMBR(*ALL). Then move *HIVAL to RRN and do a SETGT on the
file... this will take the control to the bottom of the
first member...then READ will give you first record of the
Second member...... This way we can go to the member....
(This method I tried and succeeded)...
