We can not read a pf in reverse order in CL/CLLE. As POSDBF
only set the pointer to *START or *END and once you set it
to *END and then do the read operation, end of file will
reach and there is not such condition(MONMSG) through which
you can read the pf in reverse order.
you can read a physical file in DESENDING ORDER. You can
first sort the physical file in decending order through
OPNQRYF using KEYFLD. This will sort your PF in decending
order based on your key field and then do the RCVF on this
file.
But for this you first need to do OVRDBF on the file.
