The STRNRC file:

	The STRNRC file is a site-wide equivalent of the user's
.strnrc file.  The STRNRC file is read first, and can be overridden by
the user's own .strnrc file.  The STRNRC file is useful for setting
defaults or changing something that would usually require the user to
set an environment variable.  It can also be useful if the local site
admin thinks strn should have different defaults (like follow off
or Fold on).  Here is the current STRNRC file:

----- cut -----
#### Sample system-default strn file.
### You may wish to edit this file.
### (This file is set up to follow the defaults reasonably closely)

#Score order (1) + follow mode (8)
value SAMODE 9

#Display score, author, and subject.
#This isn't the strn-default value (author added)
value SADISPLAY 26

#Look for user topic files in the default place
value SCANGROUPS %p/scangroups

#Look for scorefiles (commands) for each group in %p/scores
value SCOREGROUPS %p/scores

#Make the '+' command the default (and print other common commands)
#value GROUPDEFAULT +;nq

#Uncomment this if you want to compress the help files.
#(remember not to compress the top/index files)
#(Suggestion by Firehawk)
#value HELPPAGER zmore

Environment variables:

STARTCMD
	This variable contains a command that will be executed when
strn is first started.  Example:
#Start in the group scan mode:
setenv STARTCMD :

**** temporary hack: SVNOFOLLOW ****
SVNOFOLLOW
	If this variable is set to anything, virtual scan mode will
not start up in "follow" mode.  Example:
setenv SVNOFOLLOW TRUE

Tables [see below for usage]:

SADISPLAY
  1	article number	"32941" (default: OFF)
  2	score		"[10]" (ON) (when scoring is available)
  4	threadcount	"{17}" (OFF)
  8	author		"J. Random Luser" (ON)
 16	subject		"> Rambling..." (ON)
 32	Summary line    "Summary: more ado about nothing" (OFF)
 64     Keywords line   "Keys: ado, nothing" (OFF)

SAMODE
  1	score ordering mode	(ON)
	(If on, high-scoring articles will be displayed before
	 lower-scored ones.  See the 'o' command.)
  2	new articles first mode	(OFF)
	(If on, display newer articles before older ones if the scores match.
	 See the 'O' command.)
  4	unread+read mode 	(OFF)
	(If this is on, articles will be displayed even if they are read.
	 See the 'U' command.)
  8	follow mode ON		(ON)
	(Follow an article's thread before returning to article scan mode.
 16	Fold mode ON		(OFF)
 32	Zoom mode ON		(OFF)  (not very useful)
 64	"VI" mode (use 'j' and 'k' to move up and down.) (OFF)
	Note: If "VI" mode is on it will be used for *all* scan modes,
	      and the old 'j' and 'k' commands will not be available.
128	mark_still mode		(OFF)
	(If on, don't move the pointer after mark and select commands.)
256	(obsolete, reserved for compatability)
512	unzoomrefold		(OFF)
	(If on, leaving Zoom mode will turn on the Fold mode.
	 This can be useful on very slow terminals.)

SCOREMODE
  1	Nice Background mode enabled (if available, defaults to ON)
  2	Verbose scorefile read (ON)

SVMODE
  1	follow mode ON (ON)
  2	unread+read filter mode[*] (OFF)
  4	scoring order (ON (if scoring is available))
  8	unread+read display mode[*] (OFF)
[*]: may be reset by a virtual group command

SVDISPLAY
  1	display score (ON)
  2	display author (ON) [*]
  4	display subject (ON)
  8	display newsgroup (ON) [*]
 16	display true subject only (OFF)
[*]: may be reset by a virtual group command

Table usage:

	In the tables above, find the options you want to use as the
defaults for strn.  Each option has a number to the left of its description.
Add up the numbers for the selected options, then set the the appropriate
environment variable to the total.  Environment variables can be set with
"setenv NAME VALUE" in the C shell--other shells may use different commands.
(The C shell syntax is used in the examples below.)

	If any of the above variables are not defined, the
default values will be used for its options.

Examples are probably clearer than explanations:

#Display Article #, score, author, and subject
#           1      +  2  +    8  +    16	= 27
#Environment variable:
setenv SADISPLAY 27

#By default, start in score mode, with follow and Fold ON, and use VI mode
#                        1       +       8     +    16   +         64 = 89
#Environment variable:
setenv SAMODE 89

#Use Nice Background and Verbose read
#         1           +       2        = 3
#Environment variable:
setenv SCOREMODE 3
