q shpopts

q shpopts

Lists the current settings for drawing and writing out shapefiles.

Usage Notes

This command is available with GrADS version 2.0.a9 or later.

The clear shp command releases all user-defined shapefile attributes from memory, and resets the output filename root and shapefile type to their default values. The reset and reinit commands will do the same thing -- use clear shp if you do not want to reset all the other user settings.

Please see the documentation page on shapefiles for more details.
