LAS\DUMP [Argument] A debugging command no longer used very much. Without an argument, it lists a certain number of informations about the R Observation header (A CERTAIN number doesnot mean ALL, although it should...). With "D[ATA]" as argument, it lists in addition the data values. With "F[ILE]" as argument, it lists information about the input and output file, and finally with "I[NDEX]", it lists information about the current index.
