vsql windows

Hi am using vsql on a windows client and want to use an editor other than Notepad, such as Notepad++ or UltraEdit. I am trying to set up the vsqlrc.conf, but it is unclear exactly what to do. I created an environment variable for VSQL_HOME which points to a directory in which I have placed the vsqlrc.conf but this does not work. I also in vsql have used the /set command to point to the Notepad++ executable with the VSQL_EDITOR variable but this does not work. I need some assistance. Thanks Trevor
