I notice Guy is often mooting improvements to us in this list, so let
me moot one back.

How about enlarging the field sizes in SHOW SYSTEM. Look what I get..

MON1->sho sys /proc=*eir*
OpenVMS V7.1-2 on node MON1 3-MAR-2006 15:06:57.83 Uptime 630

MON1->

The I/O figure is too big to fit in the current display! A nice, quick
and easy way I like to use, to see what's going on in a system is to
run show sys occasionally and watch how the numbers change.

But ********* doesn't change at all!

I guess this layout was designed way back in the 70's when it was
inconceivable that anybody would do a gig of I/O without rebooting the
system (or, indeed that a system would stay up for 630 days without
needing a reboot). But that's the way things are now. Would it be an
easy job to change this? Or maybe some means of customising the
display in the command?

The greatest challenge in this type of enhancements is avoid breaking
compatibility with prior releases. Many people parse the output of SHOW
SYSTEM, and it may break existing procedures. Another concern is that
increasing the width of the field will result in the display not fitting
into
80 characters wide terminals. Personally, I always work at 132 mode
but again this is something we can't ignore.

how about adding a new qualifier /WIDTH and several keywords
allowing overriding some defaults, for example:

$ SHOW SYSTEM/WIDTH=(IO=10,PAGES=10)

What say you?
