# Mark_reference is a variable to determine the time reference for
# finding time marks on objects.  If undefined, it is assumed that the
# "mark" variables (l_mark_time, l_mark_samp, r_mark_time,...) are found
# in relation to the time location of the cursor (i.e. in relation to
# cursor_time).  If mark_reference is defined as the name of a
# "readable" variable (any global or view-specific numeric variable),
# the marks to the immediate left and right of the value of the named
# variable are referenced.  Mark_reference is both a global creation
# variable and a view-specific variable.  Mark_reference may take on the
# value of any defined global or view-specific symbol name.  Its default
# value is "cursor_time".  Of course, it can also assume the name of
# user-defined symbols.  Thus, one way to get the time locations of the
# marks immediately to the left and right of, say .34 seconds from a
# display object named bob1 with a command like:
#   send_xwaves set mark_reference my_time my_time .34:: \
# 	bob1 get aname l_mark_time r_mark_time
# Of course, if you don't mind moving the cursor, the same operation
# can be performed without redefining mark_reference, thus:
#   send_xwaves bob1 set cursor_time .34:: \
# 	bob1 get aname l_mark_time r_mark_time

# hold_audio_port is for the sparc only.  This eliminates the clicking
# (e.g., in the Sparc 10 audio) when the audio device is opened.  By
# default it is initialized to 0.  If it is set to be non-zero, then it
# holds the audio port open once it has been used once.  We think that
# the clicking results from the device reverting to single channel, 8
# bit, mulaw upon open, and then it is set to the desired mode.

# As of 5.0.x we have implemented a new global max_cmap_size which
# allows specification of the number of entries used by xwaves.  By
# default xwaves uses 128 colors in its colormap.  Thus, if entries
# are tight, one can set max_cmap_size to, say 64 or less, and still
# possibly have dynamic colormap control (i.e. it may not be 
# necessary to use -c).  This was easy fallout from implementing support
# for colormap plane depths less than 8 bits.  
#max_cmap_size 64

# In older sphere files, the "sample_count" field means total samples,
# NOT samples per channel (or records).  If this is non-zero, then the
# old format is used.  If zero, then current rule is used, which is that
# sample_count means samples per channel (like esps).  For example, the
# 1992 Credit Card CD is old format, but the sample files in the current
# NIST source directory are in current format.

# If show_current_chan is non-zero it enables the unique display of

# over.  By default it is 0.  Like other channel view specific fields,
# if you set the global like "set show_current_chan 1", then it will
# affect all views after that.  If you want to affect a particular
# view, do ". set file view_name show_current_chan 1", where view_name
# is the name of the view.  If you want to affect all views that
# already exist, then do ". set all t show_current_chan 1".
