ScanDir               PATH, NEW/S, MODE/K, SHOWALL/S, CONTAINER/S

With no arguments ScanDir rereads the current directory in the first  SRCE 
lister.  If you specify a path it will read that path into the current
 SRCE  lister.  If there is no current  SRCE  it will open a new lister.

if you call ScanDir with no arguments, and have a directory selected in the
source lister, it is the selected directory that will be read.  Also, in
this case, if you have a destination lister selected the directory will be
read into that.

MODE can specify one of  Name ,  Icon , or  Icon Action , the default is
 Name mode .

The  SHOWALL  switch causes all files to be displayed in Icon mode even if
they have no icon.

If the NEW switch is specified, it will always open a new lister.

The CONTAINER switch makes ScanDir read the parent of the path/file that you
give, leaving the file/dir selected.

For example, 'ScanDir F2:Games/ CONTAINER' will read path F2: into a lister
leaving the directory 'Games' selected.
