RE: Accessing files In QTEMP and the utility of multi-memberfile s

We used to use WRKMBRPDM to do file transfer from a multi member file back
when we used ETU.  Wrote a PDM pseudocommand that called a CL that did a
PWRFROM3XB and then renamed the member if the transfer was successful.  The
WRKxxxPDM commands have a lot in common with X-Tree.  

I don't use multi-member files a lot, but every now and then they come in
handy.  They are a logical, if not necessarily sensible, consequence of an
object based definition of files.  If you use them carefully, they are about
as harmless as anything else. <g>
