Useful pointers for Selected_output

[Charlie]

For specifying output location/type:

SELECTED_OUTPUT
    -file                 my_output_example.xls   #  .xls is for Windows 95-03 versions

SELECTED_OUTPUT
    -file                 my_output_example.xlsx   #  .xlsx is for more modern Windows versions

SELECTED_OUTPUT
    -file                 my_output_example.csv   # This will print in single cells which will need separating later

SELECTED_OUTPUT
    -file                 my_output_example.sel   #  Can open in Excel - essentially a worksheet
