<br><font size=2 face="sans-serif">This is a re-send of inquiry sent yesterday.
Perhaps no one in user community has actually used the shape file feature.
If so, then this is intended for the person who contributed this
function to v1.9.0-rc1 for Windows. All I need is an EXAMPLE or two
of the correct syntax when an "object" is involved, any additional
required command arguments, and any pre-requisite commands.</font><br><br><font size=2 face="sans-serif">I had done a search of the user archives
regarding shape files, but found only my previous relevant questions and
partial responses.</font><br><br><font size=2 face="sans-serif">Thanks--</font><br><font size=2 face="sans-serif">Stephen McMillan</font><br><br><br><table width=100%><tr valign=top><td width=40%><font size=1 face="sans-serif"><b>Stephen R.

I want to be able to control individual shape poly fills within the inclusive
boundaries, such as states/provinces, of the shape file. I am currently
experimenting with the "admin98" set. The associated .dbf file
contains 14 columns/fields of geographical data, including what appear
to be unique identifiers (US20, USA-KAN, etc.).</font><br><br><font size=2 face="sans-serif">The command line output indicates the

a text file as input, where individual shapes (such as state/province boundaries)
are associated with temperature or some other variable.</font><br><br><font size=2 face="sans-serif">I am using GrADS v1.9.0-rc1 (installed
