Example

INTERFACE DISP
      .
   PARAMETER DISPLAY
         .
      RPATH 'TEMP.DEVICES;"SAI_USER:DEVICES";"LSAIDIR:DEVICES"'
         .
   ENDPARAMETER
      .
ENDINTERFACE

Then if the parameter DISPLAY was given the value ARGS, the system attempted to use the object TEMP.DEVICES.ARGS then, failing that SAI_USER:DEVICES.ARGS and so on. (Note that ADAM no longer uses a `DEVICE dataset' object when opening graphics devices.)
