Opus 5 Utility Requesters
The Diskcopy Requester
This function allows you to make an exact copy of one disk on another.
When this function is called, a requester with several buttons appears.
*** See Fig 14-01 ***
From..: This list contains the possible disk drives that may be used as
the source. When you click on one, it becomes the selected
drive.
To..: This list contains the possible destination drives which are
compatible with the selected source drive. The source disk drive
is always available as a destination to allow you to make single
drive copies. This only makes sense with removable media such as
floppy drives as it would accomplish nothing to copy a hard drive
to itself.
Directory Opus 5 185
Verify: This button allows you to turn off the integrity verification
when writing data to the destination drive. Although it is
faster, you probably won't want to do this.
Bump Name: This button allows you to change the volume name using the
same naming convention as Workbench's Diskcopy. (See
AmigaDOS documentation for details.)
This function will not copy any protected software, or non-AmigaDOS
format disks.
Selecting the 'Diskcopy' button will start the copy. The 'Cancel' button
will abort without attempting to copy the disk.
*** See Fig 14-01 ***
186 Directory Opus 5
The Format Requester
This allows you to format a new disk. All new disks need to be formatted
before the computer can write to them.
*** See Fig 14-02 ***
When the Format command is called, a requester with several buttons
appears. On the left side is a list containing the devices which can be
formatted using this operation. The selected device is highlighted. Be
sure the device you intend to format is the one that is highlighted!
+----------------------------------------------------------------------+
| Warning! This option will destroy existing data on a disk. Be sure |
| you want to erase the data before you click Format or |
| Quick Format buttons. |
+----------------------------------------------------------------------+
Name: This field allows you to give a volume name to the drive to be
formatted.
Fast File System: This allows you to format a device using the Fast File
System option of AmigaDOS. You should consult
AmigaDOS documentation for more detail.
International Mode: This allows file and directory names to include
accented characters.
Directory Caching: This will decrease the capacity of your disk but the
directory reading speed will be much greater.
Put Trashcan: This button allows you to put a trashcan in the root
directory of the newly formatted device.
Directory Opus 5 187
Make Bootable: If this button is selected, Opus 5 will install a
standard AmigaDOS bootblock on the disk, making it
bootable.
Verify: This button allows you to disable the format verification. As
with the Diskcopy function, the process is faster with Verify
turned off, but you won't be made aware of any errors, so it's
better to leave Verify turned on unless you trust your disks
completely (you really shouldn't).
Format: This button begins the formatting process. Be very careful that
you have selected the correct device. Once a Format begins, it
can be aborted, but data will be lost!
Quick Format: When this button is selected, the disk will be initialised
(wiped). This provides an extremely fast way to erase an
old disk. It will not work on new disks however, only on
disks that have previously been formatted.
Cancel: This button will abort the process without attempting the
format.
*** See Fig 14-02 ***
188 Directory Opus 5
The Print Requester
This Requester gives you full print formatting control for text files.
+-----------------------------------------------------------------------+
| These configuration options work in accordance with the Amiga Printer |
| Preferences. The Amiga Preferences may override these preferences or |
| simply make the output look silly. For example, you may not be able |
| to use these options to display more lines on a page than is |
| specified in Amiga Preferences. All printers are not created equal. |
| Some printers will ignore some of these configuration options. |
+-----------------------------------------------------------------------+
*** See Fig 14-03 ***
You may adjust the following configuration items:-
TEXT
Left Margin: This field contains the number of characters to skip before
printing each line.
Right Margin: This field contains the number of printed characters
allowed on each line. The Left Margin characters are not
included in this value. For example, a Left Margin of 5
and Right Margin of 70 will result in the last printable
character in the column 75.
Tab Size: This field contains the number of spaces to which a tab
character is equivalent. Opus 5 converts tabs to spaces and
will insert the appropriate number of spaces to create columns
Directory Opus 5 189
based on Tab Size. For example, a Tab Size of 8 specifies Tab
positions of 8, 16, 32, 40, 48, 56, and 64.
Quality: This button cycles between Letter, and Draft. Some printers
can be toggled between Letter and Draft quality printing.
Pitch: This button cycles between Pica, Elite, and Fine. These values
specify the size of letters to print. Your printer will
determine the exact dimensions of these values.
Output: By default, the output will be sent to the current Preferences
printer. However, you can redirect the output to a file of your
choosing.
Printer: This option directs output to the printer.
File: When this option is enabled, output is directed to a selected disk
file or device. When printing starts, a file requester is
presented. Enter the file path required or enter the device name,
such as PAR: or SER: etc.
Header/Footer
Configuration: This button cycles between Header and Footer. The Title,
Date and Page no. buttons can be used when creating a
Header or Footer line for each page in the print out.
When the configuration button is Header, these buttons
affect the Header line; otherwise, they affect the Footer
line. By default, neither are created.
Title: When checked, a title will be generated. By default, the
filename will be the title. However, you can override this by
putting text in the Title field. You can have different titles
in the header and footer lines.
Date: When checked, the current date will be printed. Usually this is
enabled for either the header line or the footer line, but not for
both.
190 Directory Opus 5
Page No: When checked, the page number will printed. Usually this is
enabled for either the header line or the footer line, but not
for both.
Style: This button allows you to modify the appearance of all the
printed text except the headers and footers. (Some printers do
not support all of these styles.) Clicking on the Text Style
Cycle button allows you to choose from the following options:
Normal, Bold, Italics, and Unlined (Under Lined).
Print: When you click this button, Directory Opus 5 will begin printing
the information.
This function will print all selected files, one at a time with a form
feed sent to the printer between each file.
If you select only one file to print, the print routine will be started
up as a separate process, allowing you to continue working with Directory
Opus 5. To cancel this type of print, simply select the print function
again. A requester will appear asking if you want to continue with the
print or halt it. This requester will also appear if you attempt to quit
Directory Opus 5 while a print operation is in place, as you cannot quit
until the print has finished.
Even if you abort a print, the printer may not actually stop for some
time. This is because most printers have buffers, some quite large ones,
which store data for printing and will need to empty themselves before the
print out will stop.
Cancel: This button will abort without attempting to print.
Directory Opus 5 191
The Opus 5 Viewer
When required, Directory Opus 5 uses its own in-built program to display
selected files in ASCII, ANSI, or HEXadecimal formats.
The viewer opens as a separate window either on the Opus 5 screen or on
its own screen. The viewer's display is fully buffered so you may scroll
backwards and forwards in the file as required, using the scroll bars or
the keys. You may re-size the window as required with the size gadget on
the bottom right.
*** See Fig 14-04 ***
The name of the current file is displayed in the window title bar, along
with various details about the creation date and size of the file being
displayed. The following keys are active:-
up or down arrows Move up or down a line
U Moves up a page
D Moves down a page at a time
Cursor keys Move up or down a line
Cursor key + Shift Moves one page
T or Cursor up + Ctrl Moves to the top
B or Cursor down + Ctrl Moves to the bottom
Q or Esc Exits the viewer
Space Page Down
Backspace Page Up
P Print file
S Search
N Next search
Right Amiga + C Copy to clipboard
The arrow keys and PgUp, PgDn, Home, End are also available.

The Viewer Menus
The File Menu
Next: If you have selected more than one file, the next one will be read
when you exit. To exit without reading the next file, press the
'Quit' button.
Search: Searches for a string. Limited pattern matching is provided by
using the '?' character.
*** See Fig 14-05 ***
Repeat Search: Continue the search from the current position using the
same search pattern.
Print: Prints the current displayed file.
Save As: Saves a copy of the file using the standard ASL file requester.
To Editor: Lets you edit the file with your preferred text editor as
specified in the Settings/Pick Editor menu item.
Quit: Quits the viewer.
The Settings Menu
Tab Size: Allows you to specify how many spaces to be used in place of
any TAB ($09) characters found.
Mode: Choose to display the file in either normal, ANSI, or Hexadecimal
mode.
Directory Opus 5 193
ANSI mode: Some text files may contain imbedded ANSI sequences to
provide extended formatting of the text using Bold, Italics
and other sequences. When set in this ANSI mode from the
menu, the Viewer is capable of displaying most of the
standard ANSI sequences.
Hex mode: The viewer can display files in hexadecimal format. This
allows you to view binary files and other files containing
non-textual characters. The file is displayed in the
following manner: The first value is the offset, displayed in
hex. This is the number of bytes you are into the file. The
next four values are each a four byte longword, with the
actual ASCII representation at the end. Any non-text
characters are shown as a '.' character.
Use Screen: Toggles whether the Viewer is opened on the Opus 5 screen or
its own screen.
Pick Screen Mode: Allows you to choose the screen mode to use for the
Viewer.
Pick Font: Allows you to choose the font to be used to display the text
in the Viewer.
Pick Editor: Allows you to choose the command line used to invoke an
external text editor. The "%s" will be replaced with the
name of the file. For example:-
Ed "%s"
This will start a text editor called 'ed' if you have one. The double
quotes are there so that filenames with spaces will work.
Save Settings: Saves the current Viewer settings to disk.
