Printing by appending to a file

You must have !Printers loaded for 'appending to file' to operate

properly. If !Printers is quit after setting this then printing will

overwrite the file rather than append to it. Refer to Setting up for

printing

in the RISC OS 3 User Guide for more information.

Using HForm

The large file allocation unit that HForm presents to you can be

initially too small for large discs. When you press Return, HForm

detects that the quantity specified is too small and prompts you

again with the next larger file allocation unit.

Using MODE in BASIC

In BASIC, the MODE command has been extended. Where before it

used to take a mode number, now it can also take a pointer to a

mode selector or a mode string. A mode selector is passed to

OS_ScreenMode, whereas a mode string is passed to *WimpMode.

The result is that if a program changes screen mode using a mode

string, e.g. MODE "X800 Y600 C256 EX1 EY1", then when the

program finishes that will be your desktop mode.

it should also be noted that the C/G option in the mode string is

implemented by *WimpMode. Hence, MODE MODE will select a

default palette mode for the given current mode depth. This means

that if a grey mode is selected by MODE "X800 Y600 G256 EX1 EX1"

then MODE MODE will revert back to the coloured palette.

Using the Acorn Risc PC on an installed network

The Acorn Risc PC provides a more structured hard disc

environment than earlier Archimedes computers. Before attaching

your Acorn Risc PC to an existing network, it is recommended that

you first familiarise yourself with the differences between the Acorn

Risc PC and your existing Archimedes computers. To help you with this

Acorn Customer Services has prepared an application note

(number 251) to guide you on how to integrate an Acorn Risc PC

into your existing network.

If you use the SetStation utility you will need version 2.03 or later.
