Tom,
I may not be flexible enough but I kicketh myself in the butt.
I had my original .dbfawk file in the config directory and when I put in
the CVS version, pointlm.dbfawk was put in and the two were fighting.
I had the command syntax right but xastir must have been confused by
seeing both and did whatever to display the cul-de-sacs.
Thanks again,
Richard, N6NKO

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.
Or modify MTFCC=C3 so it's more selective. It is currently matching anything
that has an MTFCC that begins with C3.
Conversely, if the shapefile has mostly features you don't care about, set
display_level=0 in BEGIN_RECORD, and explicitly set it to something else for
each MTFCC code you *do* want displayed.
Alternatively, use ogr2ogr to create a shapefile that doesn't even have those
features in them. This will speed things up tremendously if there are lots
of features being skipped over in dbfawk processing. The up-front effort is
greater, but the payoff is faster map rendering.
