The primary documentation for the USE facility is in USE.RNO and
the corresponding USE.MEM.  These files are identical to the
paper to be published on this subject in the FALL 80 DECUS
Symposium Proceedings.  Read them over carefully for information.
I apologize for the lack of a help file.
      
Installation of USE.
USE is installed by making the following definition in each
user's login.com file:
      $ USE :=$DBA0:[SYSMGR.USE]USE
modified to reflect the actual disk and directory on which USE
resides in your system.
In addition, USE refers to a logical name of DF: which on my system
is defined in each user's login.com to point to their default
disk and directory.  This is referred to only in USE.FOR.
What is needed is a pointer to some area in which the user
will definitely have write access.
Note that SYS$LOGIN doesn't include the device and may not suffice
for this on some systems (such as mine).
A line such as:
      $ ASSIGN 'f$logical("SYS$DISK")''f$directory() DF
in each user's login.com will do the trick nicely.
      
USE.USE is included so that you can modify USE if you wish.
      
To install a system-wide default USE file (I use USE.DFT
as provided here), put the following line in your SYSTARTUP.COM:
      $ ASSIGN DBA0:[SYSMGR.USE]USE.DFT USE_DEFAULT
where, as usual, you stick in the disk and directory where these
files are on your system.
