The XVAREDIT procedure is a utility that provides a widget-based editor for any IDL variable. Use the input fields to change desired values of the variable or array. Click “Accept” to write the new values into the variable. Click “Cancel” to exit XVAREDIT without saving changes.
Note: When XVAREDIT runs in the IDL Virtual Machine, variable values can be displayed, but not edited.
This routine is written in the IDL language. Its source code can be found in the file xvaredit.pro in the lib/utilities subdirectory of the IDL distribution.
