  DCL Commands and Logical Names? 
 The Question is:
 
How do you undefine something?
 
I used the wrong command and put ora_root in the sytem table:
 
define/system ora_root $disk0:[oracle8.]
it should have been
define/process ora_root $disk0:[oracle8.]
 
The redefinition did not remove the first one
from system.  How do you take the first definition out?  It causes a logical of
ORA_SYSTEM to be used.
 
 
Thanks,
 
Sue
 
P.S. The documentation and help functions did not appear to have a cure for
 this problem.
 
 The Answer is:
 
  The chapter on logical names that is included in the OpenVMS User's
  Guide has a section entitled "Deleting Logical Names", which points
  directly to the DCL command DEASSIGN.
 
  The OpenVMS DCL dictionary includes the following statement, as well:
  "You can also use the ASSIGN command to create logical names. To delete
  a logical name from a table, use the DEASSIGN command."
 
  The OpenVMS Wizard encourages skimming both the OpenVMS User's Guide
  and the DCL Dictionary.  Additionally, books on DCL programming are
  availavble.
 
  The on-line OpenVMS documentation set and bibliographic information
  are both referenced in the OpenVMS FAQ.
