As nearly everything, options are also case independent.
The internal commands support only four options, because this is
easier to remember. These options start with a dash (-) followed by
one character.

  1. -C (means Clear) , used by  AVAIL , ENDCLI , LOCATE , PATH , RESIDENT 
  2. -R (means Recursive) , used by  COPY , DELETE , DIR , LIST , JOIN ,
               MOVE , PROTECT 
  3. -Q (means Quick) , used by  DIR , JOIN , LIST , DELETE 
  4. -S (means Sort)  , used by  COPY , MOVE , PROTECT 

Instead of -R you could also use ALL , if  FLAGS ALL ON  is set.

For some special cases there are longer options used: "delete bla force"
FORCE is here an option. You can abbreviate this by a point
(see  CONFIG DOT ), so "delete bla f." is the same.

To avoid a filename, that is equal to an option, to be treated as an
option you have to surround it with quotes:
      copy "-r" ram:     {to copy the file -r to ram:}
      delete "force"     {to delete the file named force}
