Limit in DIR filesize....

Willem Grooters — Wed, 10 Dec 2003 02:48:14 GMT

VMS 7.3-1, BIG files:
If a file exceeds 9999999 blocks, DIR cannot show the size properly:

BPS2004A> dir dka200:[backup]/siz

Directory DKA200:[BACKUP]

BCK100.BCK;4 6459831

Total of 1 file, 6459831 blocks.
BPS2004A> dir dka300:[backup]/siz

Directory DKA300:[BACKUP]

BCK200.BCK;6 *******

Total of 1 file, 14250159 blocks.
BPS2004A>

Is this a bug or an (undocumented) feature?

(Dir/full has no porblem. Just dir/siz. dir/siz=all has the same problem for both used and allocated sizes:

BPS2004A> dir dka300:[backup]/siz=all

Directory DKA300:[BACKUP]

BCK200.BCK;6 *******/*******

Total of 1 file, 14250159/14250159 blocks.

You can specify a /WIDTH=(SIZE=n) on the directory command to set the width.
I always use /WIDTH=(FILE=36,SIZE=8).

Use $dir/full instead

Hello Willem,

this is a way old issue (I've encountered that first about 10 years ago). Given the "****" I always suspected dir might be written in Fortran, which behaves exactly like that in case you try to format a number which is too large ;-)

Greetings, Martin

DIRECTORY appears to be written in BLISS. I suspect this is a documented feature. The width of the size field defaults to 6 before VMS V6.0 and 7 from V6.0 onwards (according to HELP DIRECTORY /WIDTH)

There is a similar problem with SHO DEV D when your LUN is larger than 499GB :-)

you can also specify the width there as well.

Upgrade to V7.3-2!

$ SET PROCESS/UNIT=BYTES

will cause DIRECTORY (and most other places where file sizes are shown) to display file sizes as bytes, KB, MB, GB, TB, or PB (as appropriate).

Your example file would display as:

BPS2004A> dir dka300:[backup]/siz=all

Directory DKA300:[BACKUP]

BCK200.BCK;6 6.79GB/6.79GB

Total of 1 file, 6.79GB/6.79GB

$ SET PROCESS/UNIT=BLOCKS (V7.3-1 behaviour) is the default.

As mentioned earlier,

DIRECTORY/WIDTH=(field:width,field:width...)

can be used for fine grained control of the directory display. It's been around since about V5.0

To all:
I _should_ have read the manuals. But it's a long time ago that I've seen files this big, so I just ran into it and wondered about it.
Since files are getting bigger and biggger (thanks to databases...) it would be a nice consideration to enlarge this default output to 8 or even 10 positions. (Guy, keep this in mind for 8.2....)
