Hints and Tips
4.9
•   Beware spaces − There is a problem with spaces at the end of OS
variables:
4.9
If you include in a !Run file code such as the following:
4.9
Set ThisApp$Dir <Obey$Dir>
4.9
Run <ThisApp$Dir>.!RunImage
4.9
then beware that you don’t include a space at the end of the first line!
If you do, the space will be included in the definition of ThisApp$Dir
and the second line will cause a “Bad File Name” error. Hugh Eagle.

•   PC emulator with an ARM3 − The default boot-up process for the ARM3
performs an RMClear command, killing all RAM resident modules including,
in particular, the module that drives the ARM3. So, in order, to get the
PC emulator to take advantage of the ARM3‘s extra speed you need to
alter the line in !PC.Genboot.!Config immediately after the one that
reads “Perform RMClear?” from “Y” to “N”! (Thanks to Martin Coulson of
Atomwide for this advice.) Hugh Eagle
4.9
•   Printer tips − You can alter the halftone density by editing the
PrData file within your printer driver (see Archive 4.6 for an example
of how to find this). For instance, PrinterLJ has lines such as:
4.9
pxres_halftone:300/8
4.9
pyres_halftone:300/8
4.9
so each halftone dot is actually formed of a matrix of 8x8 dots, giving
a halftone density of 300/8=37.5 dpi. This gives a very coarse effect
but can produce 65 different grey levels. Altering the lines to:
4.9
pxres_halftone:300/6
4.9
pyres_halftone:300/6
4.9
gives “only” 37 grey levels and a dot pitch of 50 dpi. Experiment to see
what suits your printer best.
4.9
A word of caution. I used !Draw to produce some PCB artwork, printed it
out using !PrinterLJ on a DeskJet Plus and sent it off... Disaster! The
size was OK across the width but was 1.5% too small along the length of
the paper, as was discovered when the finished circuit boards came back.
I’d previously had no trouble using an Epson-compatible printer, so it
may be something to do with the friction feed on the HP slipping, or
perhaps a slightly thicker paper would have helped. Anyway, if your hard
copy must be accurate, then check it! Jonathan Oakley, Cambridge.
4.9
•   Printing * command output − Ever since I got my LaserDirect I have
been laboriously printing the results of *Status, *Dump, etc. by
directing the output to a file and then printing the file (while
bemoaning the loss of the <Ctrl-B>, etc. facility à la BBC). However, I
have just realised that it is easier (and much more in keeping with
Acorn’s RISC-OS standards, I am sure) to open a Task Window in !Edit,
enter the * command (which puts its output in the window) and then print
the contents of the window by “saving” to the printer driver icon. In
other words, click <menu> on the !Edit icon on the icon bar and use
Create − New Task window. This presents you with a new window with a *
ready for a command. Type in the command whose output you want listing,
say, *STATUS. When the listing has finished, click on the window with
<menu> and go Edit − Save and drop the text file produced onto your
printer icon. Easy! (Then close the window, answering ‘Yes’ to ‘Kill and
close’.) Hugh Eagle
4.9
•   Printing via a RISC-OS printer driver from a BASIC program − Have you
ever wondered why your computer has a button called “Print” that doesn’t
seem to do anything of the sort?
4.9
At last, applications seem to be appearing that recognise that pressing
the <Print> key is rather an intuitive way of printing (Impression and
Poster are two examples). Also, I have discovered that RISC-OS printer
drivers are not nearly as fearsome as the PRM makes them seem and it is
actually quite easy to incorporate into your own program’s printing
routines which are activated by ... wait for it ... the <Print> key.
Amazing!
4.9
Take the Painting application from the original Arthurian Welcome disc,
for instance. We still use this in my family because it is so simple,
but it has always (incredibly) lacked a printing facility. To rectify
this, proceed as follows:
4.9
Put this line near the beginning of the program (e.g. immediately after
PROCdesktop (at about line 200):
4.9
 PROCPrintSetup(110000)
4.9
Note: 110,000 bytes is big enough to allow the program to run in mode
20. 55,000 would be enough for mode 12.
4.9
Put this line in the WimpPoll loop (e.g. immediately after the ENDCASE
statement at around line 400):
4.9
IF INKEY-33 THEN PROCPrint(162,232,1274,972)
4.9
Note: INKEY-33 is the crucial function that recognises whether the
<Print> key is being pressed.
4.9
Finally, put these procedures at the end of the program:
4.9

•   Running one application from inside another If you’ve ever been
puzzled by odd behaviour when you try to run one application from inside
another, the following advice from Mark Neves of Computer Concepts’
Technical Support Department may help.
4.9
My particular problem arose when I tried to make sure that a printer
driver was loaded by running !PrinterXX from within application A’s !Run
file. The result was that application A failed to run and when I quit
!PrinterXX, an error was reported.
4.9
The answer is that when you run a “sibling task” from another appli
cation’s run file the sibling “takes over the current environment” until
it terminates and only then does it return control to the parent task
(in a manner analogous to a subroutine call).
4.9
The solution is to use the command
4.9
* Desktop <sibling task name>
4.9
rather than *Run.  Hugh Eagle
4.9
•   “Saving” data from one application to another − (This is another of
those “obvious to those who know it” hints.) If you want to transfer
data (e.g. text or a sprite or a drawn object) from one RISC-OS
application to another you don’t have to save it on a disc from
application A and then load it into application B; all you have to do is
drag the icon from application A’s “Save” box (i.e. the window that
appears when you choose a Save menu option) into application B’s window.
4.9
This works with all well behaved (“RISC-OS compliant”) applications,
e.g. !Edit, !Draw, Impression, !Paint, !Poster, etc. and generally works
for either the whole contents of a window or for selected items. Hugh
Eagle
4.9
•   Sprite plotting and colour translation − The ColourTrans section of
the PRM (pages 1399 to 1424) includes references to a number of SWI’s
(including, in particular, ColourTrans_SelectTable) which have to be
called with R1 pointing to the “source palette”. Since, according to PRM
pages 390−391, a sprite’s palette data starts 44 bytes after the
beginning of the sprite, it seems clear that, in order to translate a
sprite’s palette you simply call the ColourTrans SWI with
SpritePointer%+44 in R1, doesn’t it? Wrong!!!
4.9
In fact, the palette data in a sprite appears to include 8 bytes for
each colour with the second 4 bytes duplicating the first 4 (does anyone
know why this is?) whereas ColourTrans expects only 4 bytes per colour.
4.9
So, before you can translate a sprite’s colours, you need to include
some code on the following lines:−
4.9
PaletteLength%=SpritePointer%!32−44
4.9
IF PaletteLength%=0 THEN
4.9
 PalettePointer%=0
4.9
ELSE
4.9
 FOR I%=0 TO PaletteLength%-8 STEP 8
4.9
  Palette%!(I%/2) = SpritePointer%!(I%+44)
4.9
 NEXT
4.9
 PalettePointer%=Palette%
4.9
ENDIF
4.9
Note: The palette data, if any, starts 44 bytes after the beginning of
the sprite. SpritePointer%!32 contains the number of bytes from the
beginning of the sprite to the start of the actual sprite pixel data. If
this equals 44, there is no palette.
4.9
The point of setting PalettePointer% to 0 if there is no palette data,
is that if the sprite has no palette then, in many cases, (especially if
the sprite is defined in a 256 colour mode) it makes sense to call
ColourTrans with R1 set to 0 since ColourTrans will then translate the
default palette for the sprite’s mode. However ...
4.9
•   Strange sprite colours − Ever since RISC-OS arrived, I’ve been puzzled
by the odd colours which have appeared when some sprites have been
plotted by various applications (including Impression, no less). I think
that, at last, I’m beginning to understand why. Consider the following
curious state of affairs:
4.9
Palette details are an optional part of the sprite data format. A lot of
sprites are created by !Paint. !Paint, by default, creates sprites
without a palette (presumably on the assumption that, having been
designed in the Desktop colour scheme, they will be used on the
Desktop.)
4.9
The PRM (page 1278) recommends that you should use the ColourTrans
module for best results when plotting or printing a sprite. However,
although ColourTrans knows how to translate from any given palette and
from the default palette for any mode, it doesn’t seem to be equipped
with any means of translating the standard desktop palette of a mode
other than the current one.
4.9
Therefore, the best that applications can do when faced with a palette-
less sprite is to tell ColourTrans to assume that the sprite was defined
in the default palette for its mode. The trouble with this is that it is
about the worst possible thing that can be done with a sprite defined to
be used on the Desktop since, for instance, colour 0 which is intended
to be white, will be translated by ColourTrans, working from the default
palette, into black! For example, even Impression reverses the colours
of its standard document icon.
4.9
So, what’s to be done? As far as I can tell:
4.9
The best advice is to make sure that every sprite has a palette. If this
isn’t possible then, for plotting sprites on the Desktop, use
Wimp_ReadPixTrans if a sprite doesn’t have a palette (this is the
routine that the Wimp manager uses for plotting sprites as icons and
seems to produce quite acceptable results on the whole) and save
ColourTrans calls for sprites that do have palettes. For example, follow
the above palette conversion routine with code something like this:
4.9
SYS “ColourTrans_SelectTable”,Mode%, PalettePointer%,-1,-1,ColTable%
4.9
IF PaletteLength%<>0 THEN
4.9
  SYS “OS_SpriteOp”,52+512,Sprites% ,SpritePointer%,200,200,
Mask%*8,Scale%,ColTable%
4.9
ELSE
4.9
  IF NumberOfColoursInSprite%<63 THEN SYS “Wimp_ReadPixTrans”, 512,
Sprites%,SpritePointer% ,,,,,ColTable%
4.9
  SYS “OS_SpriteOp”,52+512,Sprites%, SpritePointer%,200,200,
4.9
Mask%*8,Scale%,ColTable%
4.9
ENDIF
4.9
If you’re plotting to a printer, “Wimp_ReadPixTrans” doesn’t help and I
don’t think there is any straightforward, foolproof method. (It would be
possible, I think, to create a block of palette data with the RGB values
for the colours of the Desktop palette in the relevant mode and then
feed this into ColourTrans, but this would be a rather tedious process.)

Impression Hints and Tips
4.9
•   Adding fonts by using search & replace − As a mathematics and physics
teacher, I use a lot of Greek letters and it is rather bothersome to
have to work through all those menus to reach the effect “Greek” every
time. Therefore, I use search & replace in a way which (at least in the
Impression Junior handbook) is not documented:
4.9
I type the text, using the Latin equivalents of the Greek letters (“g-
Quant” instead of “g-Quant”) then, when I have finished the text, I use
the following:
4.9
   Find: g-Quant
4.9
   Replace: g-Quant
4.9
Impression does the rest. (Many thanks to Computer Concepts for the
information!)
4.9
By the way, if you wish to find out how all the other effects are saved
in an Impression document, there is an easy way to find out: Just take a
document with lots of effects and save only the text story (“with
effects”). If you then drag the icon of the saved text story onto the
!Edit icon, the text will appear with all the effects in plain language.
 Jochen Konietzko, Koeln, Germany
4.9
(Wouldn’t it be easier to use <ctrl-F6> and edit the “Greek” style, go
down to the bottom where it says “Key short-cut”, click in the box and
press, say, <ctrl-shift-F9>, then OK it? Then when you want, say, “g-
Quant”, you type “<ctrl-shift-F9>g<ctrl-shift-F9>-Quant”.... Oh, I see,
Impression Junior doesn’t have styles. Oh well, nice try!)
4.9
•   Cutting invisible text − If you have more text in a frame than will
fit, you get the little red arrow which indicates that some of the text
is invisible. You could obviously create a new frame, click on the over-
full frame and then click <adjust> on the new frame but there may still
be too much for that frame. So, is there any way of marking the
invisible text so that you can cut it or copy it? The answer is that you
simply use <ctrl-down> to move the cursor to the (invisible) bottom of
the text the click <adjust> to indicate the upper limit of the area to
be marked. Ed.
4.9
•   Handy hint − If you use the ‘hand’ to move up or down through a long
document, you are not limited in your movements to the visible page. In
other words, if you keep moving the mouse up and up (by repeatedly
lifting the mouse off the table) or down and down, you just keep moving
through the document in the desired direction. (This is particularly
useful if you are a trackerball user!) Ed.
4.9
•   Importing text files into Impression − In the new version of Impres
sion which CC have just sent me (version 2.11), I have discovered an
exciting new concept in the Archimedes world − “the Return Stripper”!!
4.9
In the Extensions directory is a new loader module called “LoadReturn”
which at last seems to deal satisfactorily with the importing of text
files. Using this, I no longer have to load the file into !Edit then
change linefeeds into carriage returns before importing. Nor do I have
to suffer fixed line lengths in the imported text.
4.9
However, I do have two quibbles (some people are never satisfied!):
4.9
Double carriage returns are reduced to single returns, so spaces between
paragraphs are eliminated (unless you change the style so that it leaves
such a space − which I think is good practice. Ed). I feel it would be
helpful to be able to set a “preference” to decide whether or not double
returns are preserved.
4.9
Importing a text file now involves a somewhat tiresome sequence of
message windows whereby I am asked to accept or reject each of the
available loader modules in turn. I feel it would be helpful to be able
to use the “preference” facility either to define which loader is used
for which filetype or, at the very least, to determine the order in
which the various loader options are offered to me. Hugh Eagle.
4.9
(All I did was to put the LoadReturn extension into the Auto directory
in the Impression directory and now when I want files stripping, I use
!Settype (Shareware 19 or 23) to change them to Acorn data file type
(&FFD) and they are stripped automatically. Ed.)
4.9
•   Labels & Tickets − Another way of doing tickets and labels is to
define a new master page which is the right size for what you want to
create (pretty radical, eh?). “Fit lots” still works, giving you
multiple tickets per sheet, but you’re not restricted to 1% size
increments which can cause you to miss the boundaries on sticky labels,
especially where there are three or four across the page width.
(Brilliant! Why didn’t I think of that? Ed. − see below.)
4.9
A similar technique works for cassette inlays. One way is to define a
single master page 101mm deep and 288mm wide, divided into columns of
16, 12, 65, 65, 65 and 65mm; this format will fit two inlays to an A4
page (assuming zero border width, which will vary between printers), but
you need to fiddle around with !FontDraw and !Draw (Or use Draw1½ − see
below. Ed) to get text on the spine of the cassette. Starting with a
page 288mm deep and 101mm wide gives you the spine text a sensible way
round, but the four “body” pages are then landscape, which you may not
want.
4.9
Another way is to split the inlay into two chapters; the spine has a
101mm wide, 28mm high master page, and the body pages are 65mm by 101mm,
or vice versa if you want landscape. Then you need to do a bit of
cutting and pasting by hand, as Impression won’t print individual pages
sideways. This is the technique I ended up by using, printing at 141%
then reducing the pasted-up result from two up on A3 back down by 70% to
A4, thus enhancing the graphics halftones from 37.5 dpi to 53.6 dpi.
I’ve included an example ... (Which we have put on the Monthly Program
Disc. Ed) Jonathan Oakley, Cambridge.
4.9
•   Labels & tickets − Ed’s version − I have played a bit with Jonathan’s
ideas and developed them a little. I tried to create some labels (like
the ones on our Shareware Discs etc which come as 24 to an A4 page) and
found that his method worked very well. I created a master page that was
70mm x 37.125mm (which is 210mm divided by 3 horizontally and 297mm
divided by 8 vertically). I set a border 3mm wide on all four sides
because the Laser Direct HiRes can print up to about 2.5mm of the edge
of the page and I wanted to have a simple line border around my labels.
I put all my text on the master page including a page number so that I
could have a serial number on the labels. I then closed the master page
and created another 23 pages for my document by using <menu> Edit −
Insert new page. I clicked 22 times with <adjust> so that the menu
stayed on screen and once with <select>. I then pressed <print> and
clicked on “Fit lots” and then “Setup...” and then “Ignore page border”.
The printout which appeared was almost right but was 1mm too far to the
right, 1mm too low at the top and the last label was even lower. (Thinks
hard.... tries various things and then....) The printout was slightly
too long so I created a slightly shorter master page − 70mm x 37.11mm. I
tried to see if there was any adjustment on the laser printer but
couldn’t find any so I went to the (new, shorter) master page, clicked
on the frame and pressed <ctrl-F10> to alter the frame. In the position
section, I simply increased X from 5 to 6 and reduced Y from 5 to 4 in
order to move the text on the page 1 mm right and 1 mm up. Bingo! Every
border on every label was almost exactly 5mm.
4.9
I also had a quick try with Jonathan’s cassette inlay printing and it is
really very easy with his first method − I cheated though by using
Draw1½ (Shareware 34). For the spine, all you do is create a new Draw1½
document, type in the text you want, change it to whatever font you are
using, press <menu> − Special − Text to path and then <menu> − Save −
Selection and drop the Draw file produced into the relevant graphics
frame in your Impression document. Then use <adjust> to drag the picture
round until it is near enough at right angles to the rest of the text
(having decided which way you want it to face) and finally press <ctrl-
F11> (Alter graphic) and set the Angle to exactly 90° or 270°. (If you
can remember which way round 90° or 270° puts it, then there’s no need
to swing it round with <adjust>.) Here is a bit of text that I have just
inserted. It must have taken me all of 45 seconds to create the frame,
type in the text, convert it and add it in! (Software to enable me to do
that on the Mac cost me hundreds of pounds a couple of years ago!)
4.9
•   “Running” an Impression document − In Alan Highet’s review of !Menon
on Shareware 38 (Archive 4.8 page 48) he mentions that it did not work
well with Impression documents since an attempt to “run” one of these
caused a second copy of Impression to appear on the icon bar.
4.9
I have observed a similar phenomenon in trying to create a front-end for
Impression which, amongst other things, opens a template document chosen
by the user. Simply *Running the document results in the loading of a
new copy of Impression regardless of whether one is already running.
4.9
So, why is it that double-clicking on an Impression document in a Filer
window will load it into an existing copy of Impression whereas
“running” it doesn’t?
4.9
Mark Neves of Computer Concepts’ Technical Support Department has kindly
explained why this happens and has pointed to a solution.
4.9
The reason is that what happens when you double click on an icon in a
Filer window is not simply that the document is “run”. First, the Filer
broadcasts a Message_DataOpen message inviting other applications to
open the document, and only if this message is returned unacknowledged
does it instigate a *Run.
4.9
The solution is a fairly simple program on the following lines:

•   Setting a style in an Impression frame − Question: how do I set up a
blank frame containing a predetermined style (for instance, to hold the
address of the person I am writing to, where I would like to use a
different font from the one in the body of the letter)? If I put the
cursor in the frame, then apply the style, then move the cursor
elsewhere (or save and reload the document) before bringing it back to
the address frame, and then start typing, the text comes up in the
Basestyle.

Answer: If after applying the style, I type anything (for instance a
couple of carriage returns) in the address frame then the applied style

Caution: if I delete the entire contents of the frame the applied style
is deleted too. So, if I want to blank the frame for reuse I have to
remember to leave a carriage return or two to preserve the style. Hugh

•   Typesetting − We said we would try to find companies willing to do
typesetting from Impression output. Here are two that we have found. If
you discover others, ask them to send us details of their services and
we will publish them. We are particularly interested in those that will
take Impression files as such rather than PostScript files on MS-DOS
discs.
