[comp.os.vms] SETUP/PREPARE

nagy%43198.hepnet@LBL.ARPA.UUCP (04/29/87)

In designing systems like SETUP or PREPARE which end up calling lots
of little command procedures... remember that just about the SLOWEST
operation DCL can do is to open a new file (for reading, writing or
command execution).  "Simple" things (a logical name or 2 and a symbol
or 2 at most) are best grouped together to avoid this problem!  For
more complicated packages, the overhead of the file open becomes less
important.  However, the long dragging wait for LOGIN to complete can
be a real pain!
