In the new 2008 Tiger maps I'd like to have the county names appear
(large, green) at about zoom level 100 and then disappear again at
about level 300. Which dbfawk file do I play with to make this happen?

How do I go about ignoring the display of a particular feature?
I don't want the "x" displayed at the end of cul-de-sac's (MTFCC
code
C3061).
What is the structure of the line to accomplish this? I am getting
nowhere.
Two ways to do it:
If the majority of features in the shapefile are features you want to
display,
set display_level to something reasonable in BEGIN_RECORD, and set
it to 0
for features you don't want. So in pointlm.dbfawk, if most
features are
features you want displayed, leave display_level where it is in
BEGIN_RECORD,
and add a dbfawk rule:
/MTFCC=C3061/ {display_level=0; next;}
Make sure that no earlier rule matches such a record first. For
example, if
you have
/MTFCC=C3/ {display_level=512; next;}
(which you do), then you must put the C3061 rule earlier in the
file so that
only those MTFCC=C3... that aren't C3061 get caught by the less
specific
rule.
Perfect - I added
/MTFCC=C3061/ {display_level=0; next;}
to the file ahead of the other aforementioned rule, and no more red
X's at the dead ends. Thanks, Tom, you really led the horse right to
the water on that one.
