DDP (Disk Directory Printer)
DDP was written with one main purpose in mind, to enable the
ST user to get complete disk directory listings including all sub-
directories. There are many options that effect the file
information listed as well as the format of the output.
First we will discuss the options that effect the file
information to be displayed.
File Information
Display
The options under display govern which information will
be displayed on the directory listing. Any items not
selected will not appear on the output.
Size
Selects file size.
Time
Selects time of file creation.
Date
Selects date of file creation.
Attr
Selects file attribute. Read/Write or Read Only.
Sort On
The options under sort on determine which criteria will
be used when sorting the listing. A file can be sorted
on an item that will not be displayed.
Name
Selects name to sort by.
Ext
Selects extension to sort by.
Date
Selects date to sort by.
Size
Selects size to sort by.
Sort By
This determines if the file will be sorted in ascending
or descending order according to the item selected.
Ascending
Sorts in ascending order. A thru Z / 0 thru 9.
Descending
Sorts in descending order. Z thru A / 9 thru 0.
Send To
DDP can send the output to many devices. The display
(CON:), RS232 port (AUX:), printer (PRN:), or file can
be selected as the output device.
Please note that if a file is selected as the output
device, a file selector menu will appear to prompt you
for the file name.
Format
There are many ways DDP can format the output. The
following selections can be used in any combination.
FF
When selected, a form feed is given before each
listing (including subdirectories).
Bold
If selected the subdirectory name will appear in
bold in order to stand out.
Headers
DDP gives the user the option to title the
directory listing. This information is placed in
the heading lines (there are 2) on the top of the
form. When headers is selected these titles will
appear before each listing (subdirectories too).
Wide
Wide enables the user to conserve paper by
instructing DDP to place as many files on a line as
possible. If the printer width is 132 columns wide
and DDP is instructed to print file names only (no
other display options are selected), then 8 names
will be placed on a single print line.
Also notice that there are 4 text editable lines on the form.
The first 2 are under the heading section. These are simply
the titles that will appear if selected. The next is the
drive spec. Any drive can be placed here. The default is
drive 'A' for any errors. Finally the last text field is the
print width line. This line is used to inform DDP how wide
the output line is. The default is 80 char but can be as
large as 999. If your printer has a compressed print mode,
use 132 columns and the wide option to pack as much
information on the least amount of paper.
One additional note, it is possible to abort DDP while it is
listing. Pressing the ESC (escape) key will cause DDP to
abort the current listing and start on the next subdirectory.
Pressing the UNDO key will terminate the listing process
fully, returning the user to the main form. These keys are
active ONLY when the "BUSY-BEE" mouse form is visable, if the
mouse is any other state or is not visable, then the abort
functions are not operational. Also, pressing the RETURN key
is the ONLY way to exit from the INFORMATION form.
This program is still in its testing stage. If you experience
any problems please feel free to leave me a message. I can be
reached at the BBS listed in the information box. The current
limitations are no more that 100 subdirectories and no more than
300 files per subdirectory. Have fun with DDP and make sure to
leave comments!
PS. DDP is under testing, it is not in the public domain so to
speak, when fully completed it will be submitted to a magazine for
print. Thank You.
