Changing size of recall buffer?

» close window

The Question is:

 
Can you tailor the size of the recall buffer?
 
We would like to limit certain users to the old recall buffer size of 20
commands. The bugger buffer in vms 6.2 is helpful for technical people, but
is confusing some users.
 
Is there a logical we can define in their login.com, or a SYSGEN parameter
that will reduce the size of the Recall Buffer.
 
Thanks in advance,

The Answer is :

 
  The size of the recall buffer is not programmable at the driver level,
  the terminal drivers know about one command only.  Additional entries
  in the recall buffer are implemented in the application, in a library
  such as SMG, or in DCL.
 
  From DCL, changing the size of the recall buffer would generally require
  you acquire and apply an unsupported patch acquired from DECUS or other
  source.
 
  You can entirely disable the recall buffer, of course.
 
  Users confused by large recall buffers may be good candidates for a local
  captive command procedure or similar environment created for this purpose.
  Alternatively, periodic RECALL/ERASE commands or similar may be of interest.
