- %H2%General
-
- %JR%This file describes gives extra information to the PipeDream 3 User Guide. Topics covered
- are:
-
-
-
-
-
-
- %H2%Fonts
-
- %JR%The PipeDream 3 User Guide implies that specifying fonts within your text only has effect on
- %JL%the printer and has no effect on the screen. This is not the case. Fonts are also displayed on
- %JR%the screen. The current slot is always shown in the system font because on most monitors it is
- much clearer and easier to edit with.
-
- %JR%To be able to display or print characters in fonts other than the system font (the system font is
- %JL%the one used by the window's title bar) the Archimedes needs to have information about the
- %JR%shapes of all of the letters. This information is supplied on disc and is read from disc when
- %JL%needed. The directory !Fonts on Applications Disc 1 contains some fonts and others may
- become available from Acorn or other sources.
-
- %JR%To speed the operation of drawing fonts RISC OS reduces disc accesses by keeping as much
- %JL%font information in memory as it can. The area of memory used for storing fonts is called the
- %JR%Font cache and you can vary the amount of memory available for the Font cache in the Task
- %JL%display off the Archimedes 'A' icon bar menu. The memory that you allocate to the font
- %JR%cache becomes unavailable to the rest of the system so it is best to keep it as small as possible.
- %JL%But if you find that fonts take ages to display because they are continually being read from
- disk you will need to give the font cache a little more memory.
-
- %JR%In order to show RISC OS where to find the directory !Fonts it is necessary to catalogue the
- %JL%disc or directory which contains it. Then, whenever RISC OS needs to read more font
- information, it will automatically read it from the disc.
-
- %JR%The file Readme_f in this directory contains a copy of this document formatted in
- %JL%Trinity.Medium. Try loading that file into a window to compare the text with that in the
- %JR%system font. If you have a dot-matrix or a laser printer and a suitable RISC OS printer driver
- %JL%you can try printing Readme_f . You may find that to obtain a reasonable speed in the
- %JR%display of fonts you need to allocate a lot of memory to the Font cache and to print at a
- %JL%reasonable speed on a dot-matrix printer you need to allocate a lot of memory to the Module
- area.

-
- %H2%Highlights in headers and footers
-
- %JR%Highlights can be inserted into headers and footers (and the title) by inserting ^n where n is the
- highlight number (similar to search and replace). For example ^4 would switch on italics.

- %H2%Z88 Filing System
-
- %JR%The Z88 Filing System provided on the PipeDream 3 disc enables you to connect a Z88
- %JL%computer to the Archimedes and load files from it and save files to it as if it were a disc drive.
- %JR%In order to do this two extra pieces of hardware are required - a Z88-Archimedes lead and
- %JL%the PC-LINK EPROM card plugged into the Z88. Both of these components are available
- separately from Colton Software.
-
- %JR%To start the Z88 double-click Select on the Z88 icon on the PipeDream 3 disc. The Z88
- %JL%Filing System will load and install its icon on the icon bar. Ensure that the lead is connected
- %JR%securely to both computers and that the PC-LINK EPROM card is inserted and running in
- %JL%the Z88. Now click Select on the Z88 icon on the icon bar. A directory viewer should appear
- %JR%showing the devices available on the Z88. Click Select on one of the devices and a directory
- viewer will appear showing the files and directories currently in the device.
-
- %JR%If you receive the message "Failed to synchronise with the Z88 (Is PC-LINK running on the
- %JL%Z88?)" check that the lead is connected securely in both computers, and that the PC-LINK
- %JR%EPROM is correctly inserted and running in the Z88. (To start PC-LINK press []L (square L)
- on the Z88.)
-
- %JR%With the Z88 Filing System running you can copy files between a directory on an Archimedes
- %JL%disk and a directory in the Z88. You can create selections in directories on both the Z88 and
- %JR%Archimedes and copy the selections. You can also copy files from the Z88 to PipeDream 3
- %JL%running on the Archimedes either by dragging the file to the PipeDream 3 icon on the icon bar
- %JR%to load the file, or by dragging the file into a PipeDream window to insert it into another
- %JL%document. Similarly you can save a file from PipeDream 3 to the Z88 by dragging the file
- icon from the Save dialog box to the Z88 directory viewer.
-
- %JR%You can also drag files from the Z88 to other, but not all, applications. For example you can
- %JL%load files from the Z88 straight into Edit by dragging files in a similar way to that described
- %JR%above for PipeDream 3. Some applications will not be able to load or save Z88 files directly
- %JL%and the data will be corrupted when it is displayed in the application's window. Of course,
- %JR%you can copy the file into a directory on an Archimedes disc first, and then load it into the
- %JL%application. (For the technically minded, this is because the PC-LINK EPROM does not
- support random access, just sequential access.)
-
- %JR%Not all of the filing system operations are supported by the Z88 Filing System. You cannot
- %JL%use the Access, Delete or Rename commands on the Filer Selection sub-menu to operate on
- %JR%Z88 files. Neither can you create directories on the Z88 from the Archimedes; you must do
- this on the Z88 itself, using it's own Filing System.
