q shpopts
Lists the current settings for drawing and writing out shapefiles.
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.
This example shows the default values:
ga-> reinit ga-> q shpopts Settings for drawing shapefiles: polygon fill color: -1 mark type: 3 mark size: 0.05 Settings for writing shapefiles: output filename root: grads output type: line format string: %12.6f
