Another directory program...


I have written SDD for the following reasons (not in
order of importance):

- small, capable of showing file sizes
- a programming exercise
- an example for ASM beginners... maybe...


SDD has the following features:

- compact, requires less than 2k of disk space
- able to display large directories in small TPA (12 bytes per
  active, matching filename stored)
- optional suppression of size display for quick check
- optional printer output

SDD has the following shortcomings:

- nowhere near as versatile as SD
- not for use with CP/M 1.x
- slow due to use of BDOS call 35 (compute file size)

SDD will be expanded to add the following:

- optional disk file output of listing
- disk freespace display
- date/time display for capable OS (CP/M Plus, MP/M, TurboDOS)

I may think of a faster way to compute file sizes without
sacrificing RAM.

                    DOCUMENTATION FOR SDD VERSION 1.01:


The following are sample command lines and their outputs:

[20:56 A] 4D}sdd 0:		;<-- able to specify just user number

No file(s)


[20:56 A] 4D}


Note that currently, SDD does not know about $SYS files and displays
all matching files.
