SET / SHOW DEFAULT DIRECTORY 


SD ^      Go up one subdirectory level
SD ^^     Go to top level of current directory
SD .      Go to login default directory and disk
SD <n     Go to directory in n'th entry of the SD stack. (D=1)
SD >X     Set default to [z.X] when currently in [z.y]
SD >      Traverse horizontally
SD .X     Set default to [current.X]
SD X.Y.Z  Set default to [X.Y.Z]
SD n      Set default to n'th predefined directory
SD \      Fully traverse the directory tree
SD <<     Show the SD stack
SD *      Show subdirectories under current default
SD ?      Show this SD help information
SD        Show the current default

------------------------------------------------------------------

SD ^ 
 
  Sets default to the next highest directory level.  If default is
  [X.Y.Z], execution of        will set default to [X.Y].  If the

                         SD ^ 
  current default is a top-level directory, nothing happens.


SD ^^ 

  Entering         sets default to the top level directory.  If

            SD ^^ 
  currently in [X.Y.Z], you will then be in [X] .


SD . 

  Sets default to the login default directory and disk.


SD <n 

  SD maintains a stack of the last eight directories visited.
  Entering         Sets default to the n'th previous entry in the

            SD <n 
  SD stack.  If n is omitted, 1 is assumed. 


SD >X 

  Sets default to the directory "X" at this subdirectory level.
  If the current directory is [A.B.C], then         will set de-

                                             SD >X 
  fault to [A.B.X].  If the current default is a top-level dir-
  ectory, nothing happens.

SD > 

  Sets default to the next directory (in alphabetical order) on
  this level.  If the current directory is [A.B], then success-
  ive uses of        will set the default to [A.C], [A.D], etc.

               SD > 


SD .X 

  Sets default to the subdirectory named X at the next lower level.
  If the current default is [A.B], then         will result in de-

                                         SD .X 
  fault of [A.B.X] .


SD X 

  Sets default to directory [X] on the current device.  Note that
  square brackets are not required around the directory name; they
  are allowed, however.  Examples:

	$  SD MYDIR         $  SD NEWDIR.A.B

  You can also move to a different device, by executing:

	$  SD device:directory

  The colon is required; you may follow the colon with a blank.
  If you just enter a device, you will go to your current default
  on the new device (e.g. from UDISK0:[X.Y] to UDISK1:[X.Y]).


SD n 

 Sets default to the n'th predefined directory.  These are usually
 defined at login, using global symbols SD__n.  You can define or
 redefine these yourself, as in the following example:

	$ SD__2 == "SYS$SYSDEVICE:[MYDIR.MYSUB]"

 Such definitions last until you logout or redefine them.  If you
 want them to be permanent, put them in your LOGIN.COM file.

 Note that you must include the square brackets in the definition.

 The definition can also be of a device only, such as "_DRC0:" or
 "SYS$SYSROOT:".  If so, then you can combine it with another en-
 try, such as:

	$  SD 1 X.Y.Z

SD \ 

   Fully traverses the directory tree under the current master dir-
   ectory, starting at the current default.  For instance, if the
   current directory is [A.B], then successive uses of        will

                                                        SD \ 
   set the default to:

   [A.B.B1]  [A.B.B2]  [A.C]  [A.C.C1]  [A.C.C1.C1X]  [A.D]  etc.

   If the traverse starts from a master directory, then ALL of the
   tree under it will be traversed; the above example starts in the
   middle of the tree, and shows that parts of the tree 'before'
   the starting point (in alphabetical order) are not traversed.


SD << 

  SD maintains a stack of the last eight directories visited.  En-
  tering         displays the SD stack, with the current directory

          SD << 
  at the top.

  Entering         sets the default to the corresponding entry.

            SD <n 


SD * 

  Entering        builds display on VT100 screen showing subdirec-

            SD * 
  tories under the current directory.  When the display is com-
  plete, enter a blank to continue, or enter any of the following
  EDT keypad commands to travel through the display:

	up-arrow	TOP	   ADVANCE	SECTION	    ctrl/w
	down-arrow	BOTTOM	   BACKUP	LINE

  Only four levels of subdirectories are shown; if lower levels
  exist, the parent directory shows an arrow pointing to the
  right.  If a directory name is too long, it will be truncated
  and a diamond will be displayed after it.  If the terminal width
  is 80 columns, truncation will occur for names longer than 13
  characters; if the screen is set to 132 columns, truncation will
  occur after 26 characters.


Errors 

  SD checks for the existence of the directory being entered, and
  prints an error if it is not found, or if the device is not
  mounted.

SDENTRY 

  If a file "SDENTRY.COM" exists in the new directory, it is exe-
  cuted.  This allows symbol definitions, etc. related to that
  directory.


SDEXIT 

  If a file "SDEXIT.COM" exists in the current default directory,
  it is executed before a move is made to a new directory.  This
  allows cleaning up of symbol or logical name definitions, etc.
  before leaving the current directory.  Normally, this feature
  would be used in conjunction with SDENTRY.


Multiple functions 

  In certain cases, SD can do two functions in one call.  Blank(s)
  must separate the functions.

     A.  A  *  can be done after all operations except SHOWs:

	$  SD X.Y *

     B.  You can do a DIRECTORY after all operations except SHOWs:

	$  SD >X DIR /DATE    (you MUST use the abbreviation DIR)

     C.  On GO operations, you can have it do another movement:

	$  SD . .Y    (go to subdirectory Y of login default dir.)

	$  SD ^ ^     (go up two levels; note difference
						      from SD ^^ )

	$  SD <3 >X   (the explanation of this is left as an
					     exercise to the user)


Logical names 

  SD translates logical names if given.  For example,

                                                       SD SYS$HELP 
  will set the default to the translation for SYS$HELP.
