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

[John Hall <jhall@xxxxxxxxxxx>]

Actually the storing of source code in members of a file is a good
example of the weaknesses of multi member files.  How can you maintain
multiple versions of source code (say by date) on the 400?
Oh and keep them all in one library so that your general ledger is
functionally grouped for operational purposes?  Who created the member,
last accessed, days used, audit trails etc.

How do you, (maybe you can?), allow a user to create / delete a member
without giving them create/delete access to the file?

A member is not quite a file.  It has some of the information/security
on its own but not all.  The 400 limits you to three levels  (Library,
File, Member)  On other computers we would just use another layer of sub
directories.  Everything you can do with a multi member file you could
do with a x-tree in dos 15 years ago.

Sure I use multi member files for some things - Archiving data
transmissions by date.  But I have 3 separate transmissions (diff
Format) so three files with a member for each date.  The more logical
grouping of this would be a separate sub directory for each date with
the three files in it.
