Miscellaneous

     This directory houses  things  of  a  miscellaneous  nature.   It
contains:

     1.  An extreemly fast login.com procedure.

     2.  A command procedure to  gather  a  lot  of  info  needed  for
         performance tuning.

     3.  A command procedure that displays working set info  for  each
         user.


     In my login.com file I take the following approach:  If it can be
done  from a higher level language then do it.  I've heard quite a few
requests for more powerful features in DCL, the fact is that  even  if
DEC gave you IF-THEN-ELSE, CASE, WHILE DO, etc...  a command procedure
is a command procedure; and they're slow.  This is  the  approach  I'm
now taking with all frequently used procedures.

     LOGIN.COM contains the usual  garbage.   I've  taken  the  symbol
definitions and logical assignments out and now define them by running
SYMLOG.EXE from my new login  command  procedure  NEWLOGIN.COM.   This
FORTRAN  code  is  SO  easy,  given  a template a non-programmer could
probably simulate it with few problems.  In my particular case it  cut
my  login  cpu time by 24% and my direct ios by 76%.  24% on a heavily
loaded system can really speed things up.  You will even  notice  that
NEWLOGIN.COM   STILL   does   some   symbol   and   logical   defining
(setvpwsym.com), if that were replaced....  The nice thing about  this
is  that  if  you  happen  to  add  a definition to your login.com you
needn't put it in SYMLOG until you get some spare time.

     I run MONITOR.COM as input to loginout.exe as a detached  process
every  once  in  a while to collect a day's worth of performance data.
See STARTMON.COM for an example of its invokation.

     GETWS.COM (soon to be GETWS.EXE) displays working set information
on user processes along with the current image name.
