Nested rooted logical names?

» close window

The Question is:

 
Rooted Logicals -
 
I have a suituation where I would like to setup a rooted logical which has
 referenance to another rooted logical.
 
I have tried to do this using the following two commands, but it does not work.
 
define/system/exec  d1   dka0:[d1.]/trans=(conceal,terminal)
define/system/exec data d1:[test_user.data.]
 
Am I doing something wrong, or is this just not support.
 
Thanks
 
Jason
 

The Answer is :

    No can do. Concealed logical names must be defined in terms of physical
    devices. Here is a short DCL procedure which will resolve all logical
    names prior to defining the logical name. For your example, use:
 
	$ @DEFINE_CONCEALED D1 DKA0:[D1] /SYSTEM/EXEC
	$ @DEFINE_CONCEALED DATA D1:[TEST_USER.DATA] /SYSTEM/EXEC
 
 
DEFINE_CONCEALED.COM
$ IF p1.EQS."" THEN INQUIRE p1 "Logical name"
$ IF p2.EQS."" THEN INQUIRE p2 "Directory"
$ !  p3 = extra DEFINE qualifiers
$ !
$ Conc=F$TRNLNM(F$PARSE(p2,,,"DEVICE")-":")
$ IF F$LOCATE("<",Conc).LT.F$LENGTH(Conc)
$ THEN
$   lbr="<"
$   rbr=">"
$ ELSE
$   lbr="["
$   rbr="]"
$ ENDIF
$ trans=(F$PARSE(p2,,,"DEVICE","NO_CONCEAL")+-
         F$PARSE(p2,lbr+"000000"+rbr,,"DIRECTORY","NO_CONCEAL"))--
         (rbr+lbr)-("000000"+rbr)-("."+rbr)+"*"-".*"-"*"-rbr+("."+rbr)
$ DEFINE/TRANSLATION_ATTRIBUTES=(TERMINAL,CONCEALED)'p3' 'p1' 'trans'
$ EXIT
