Manual for Acorn Desktop C
|
| |
I've got one set of manuals - well I had the discs as well, but have disposed of them - for Acorn ANSI C release 4. I'm about to dispose of the manuals as well; unless somebody has a use for them. I'm after £10 to cover carriage and handling. If nobody replies before 1pm, i'll be disposing of them via the... more »

!SerialDev Drivers
|
| |
I'm having trouble with the serial drivers since upgrading to 5.16 on Iyonix. The Internal32 driver errors on initializing returning with 547945428. It used to initialise fine on softload 5.15 and run fine on 4.33 on a RPC and 3.71 on an A7000+ I can load the Dummy Internal and InternalPC drivers OK. The InternalPC... more »

STDumper (Further progress.)
|
| |
Been a while since I had time to work on this one, but I spent a good couple of hours on it today and managed to get started on the buffer support code for the new SmartWord filter. Although the buffer support code is now complete. The code on the level above this is missing. Therefore the program still uses the older buggy filtering code at the... more »

Length of line in !Run
|
| |
I have recently had problems in testing a tool designed to run under AMU. The 256 line length limitation seems to have been removed under DDE/AMU but limits testing outside this environment. I seem to remember that Acorn had a long line fix and wonder if if could be used outside the DDE/AMU environment.... more »

Problem with Squeeze and Virtual RPC
|
| |
My build scripts for Impact include a step in which I squeeze the !RunImage. This cuts the size of the download down, and would no doubt speed up loading from floppy disc, if anyone still does that. A user has reported a problem when running the latest Impact on Virtual RPC-AdjustSA. He gives the following error report (from a log file... more »

Using OS_GBPB from BASIC...
|
| |
I need to read 512k chunks of a file into a buffer, process the data and write it back to another file. I've got an idea that OS_GBPB is what I need for this and have knocked up a bit of code that I think will do what I want it to do based on the PRMs & StrongHlp manuals. Can't post it here at the moment, because I'm not at home.... more »

GCC on OS4.04 in RPCEmu on a Mac
|
| |
Having recently installed RPCEmu, OS4.04, on Mac Snow Leopard and prompted by an earlier post to this group I have installed gcc 4.1.1 r2 and compiled a first "Hello World". Does anyone know where the '#' key is on Mac/RPCEmu, alt-3 gives a superscript 3 in StrongED. !Chars to the rescue. Interestingly the compilation was quicker on RPCEmu/Mac that on the Iyonix.... more »

GCC on RISC OS 4.02 in RPCEmu.
|
| |
Hi all, I've managed to get RISC OS 4.02 running in RPCEmu, and I have in *Help Modules : C Library 5.53 (14 Mar 2005) : SharedUnixLibrary 1.11 (15 Oct 2007) and GCC no longer complains about missing modules. However, nothing happens when I double click !GCC and *gcc -v doesn't work. It gives... more »

Reading and setting CSD?
|
| |
Can someone please remind me the commands to both read and to set the CSD. I have looked in vain in the PRMs, The BASIC manual, and the OS manual.
