Re: read/chain record format or file name?

["rick baird" <rick.baird@xxxxxxxxx>]

read and chain to the file name.  always.  if for no other reason than this:

when working on programs where multiple logicals over the same
physical are used, and the record formats have to be renamed, you come
across a chain or a read to the record format and you have no choice
but to stop what you're doing and go up to the f specs to figure which
file you are actually working with.

unfortunately, the same goes if you run across a write or update, but
there is a different reason for that (multiple format logicals are the
only good reason for it - yuk), so I still say: cut your pain in half
(or more) - read a file, write a record.
