DSKSIZ is a program to report how much disk you are using and what your
disk allocation is.  The format of the command is:

	DSKSIZ <programmer name>

where the programmer name is assumed to be your login name if you don't
specify one.  The program first asks you if you wish to save the printed output
in a file called PURGE.LST in your aliased area.  Next it types out (and
optionally writes in PURGE.LST) your allocation and the size of all your
file directories and the size of the files you are using on the area [1,2].
Finally, it tells you whether you are under allocation or not and by how
much.  If you are over allocation, it asks you if you wish to write the file
PURDAT with the file names of what the purger would purge.

You may optionally type the switch /Q anywhere after the command DSKSIZ to
suppress asking questions about output files.

Each line of DSKSIZ output is in the following format:

    [PRJ,PRG]  n Files.  t T.  w DW.  p%  Date


This means that disk area PRJ,PRG has n files occupying t disk tracks and
w disk words (each track is 2334. words) with a storage efficiency of p%.
Date is the date of the most recently written file in the area.
