I just got confirmation from IBM that -G and -A are only valid in daemon mode.
However, as long as the index file has .ARD.ind as the last two nodes, the -B option can be used to locate the AG and APP in the file name for a stand-alone load.
The presence of ARD is key, unfortunately "arsdoc get" doesn't include the in the names it creates! You have to update file name of the .ind file.
arsload -n -B "AG.IGN.IGN.APP.EXT" -u myU -p myP
-v /u/odv744/ag-name-here.0.Reprt-General.app-name-here.ARD
