-
-
- The following files should be in the !ARCTOOLS application directory:
-
- 1. ARCTOOLS : ARCTOOLS module code.
- 2. Manual : ARCTOOLS user manual. (Text file)
- 3. ReadMe : ReadMe file (this one). (Text file)
- 4. Licence : User licence
-
- Quick familiarization:
- ======================
-
- Double clicking on the !ARCTOOLS icon will load ARCTOOLS module into the
- RMA. ARCTOOLS is then active until killed.
-
- For a quick summary of all commands provided, type:
-
- *Tools for a list of all ARCTOOLS commands.
- *Tools G for a list of all ARCTOOLS general commands.
- *Tools M for a list of all ARCTOOLS memory commands.
- *Tools D for a list of all ARCTOOLS disc and files commands.
-
- The memory and disc editors in ARCTOOLS outperform those in any utility
- ever written for the ACORN machines. You only have to use them for half
- an hour, and I guarantee you that you will throw your old memory and
- disc editor utilities away.
-
- If you are familiar with memory or disc editors then press F12 and type
- *Medit. You will be surprised for what you get!!!! But you will only
- appreciate the power of ARCTOOLS once you have read the 'Manual' text
- file. There are so many facilities provided that it is best to print
- the file 'Manual' provided in the !ARCTOOLS directory for easier cross
- reference.
-
- Read the file 'Manual' for a complete (I hope) coverage of all the commands
- and facilities.
-
- I hope you find ARCTOOLS most useful for your needs. Please send me any
- comments or suggestions. Address is in the file 'Manual'.
-
-
- ARCTOOLS requires RISC OS 3 or higher to operate properly. This is due to
- the use of some of the new SWIs provided in RISC-OS 3.

-
- - Although I have tried my best to make ARCTOOLS compatible with
- RISC OS 3, I still havn't exploited the full features of RICS OS 3
- due to the lack of the new Programmers Reference Manuals. Some of
- the new RISC OS SWIs and their parameter passings were discovered
- using ARCTOOLS itself.
-
- - I have allowed the user of ARCTOOLS to get access to the I/O memory
- space. This used to cause problems on my A310 with RISC OS 2. It
- does not seem to do so on my A5000 RISC OS 3. I don't know if this
- is due to the new Operating System, the ARM processor difference, or
- the hardware difference.
- I can not test this with different hardware. Please send me the result
- of scanning that area on different machines, with say podules fitted.
- If there are serious problems, I will have the access to that area of
- memory made optional in next versions of ARCTOOLS.
-
- - ARCTOOLS have not been tested on a machine with 8 Mbytes and higher
- of ram. I would like to know, how it behaves. How many Mega bytes does
- the *Mmap command report? How many pages are reported by the *Mpage
- command? Do the memory editors work properly?
-
- - ARCTOOLS has been tested on an A5000 machine with 4 Mbytes of ram,
- one floppy drive, one 120 Mbytes IDE hard disc, and without any
- extension modules attached. If you have a machine with different
- specifications and you are experiencing difficulties, please contact
- me so that I'll be able to update ARCTOOLS coding.
-
- - I was hoping to include ARM 6xx assembly and dis-assembly in ARCTOOLS,
- but because of the lack of information I am unable to do this at the
- moment. If you can provide such information, you will have a copy
- delivered to your door of every new ARCTOOLS version.
-
-
-
- Current known Problems with ARCTOOLS (To be removed in next versions)
- =====================================
-
-
- 1. When using any output re-direction with ARCTOOLS commands, for example,
- *mdump, *system, *event, *vector or *fdump, you will find that the
- text output is oddly formatted. This also occurs if any of the above
- ARCTOOLS commands is issued from within the desktop Task Window. The
- reason for this is that these commands use the OS OS_Byte 134 to read the
- current text cursor position. OS_Byte 134 returns a value of 0 for the
- current X position of the text cursor if the output is re-directed. This
- seems to be a bug of the Operating System, not ARCTOOLS.
-
- 2. The current version of the disc editor can only remember one disc
- drive. When switching between the memory and disc editors using the
- CTRL+"E" key combination, the drive accessed is drive 0. This is because
- ARCTOOLS remembers the last drive it used in the disc editors. Use
- *Dedit 4, to access the hard disc, sbusequent editors switching will
- automatically access drive 4.
-
- 3. When in the disc editor, if the disc is changed, ARCTOOLS knows about
- this whenever you use any of the disc operation. ARCTOOLS will give
- the error message 'Disc changed' then it will read the new disc
- sector data at the current address. A bug exists which causes subsequent
- operation to give 'Disc changed' error message although the disc has
- already been identified.
- To prevent this, any time you change a disc while in the disc editors,
- you should use CTRL-I to install the new disc so that ARCTOOLS forgets
- about the previous disc.
-
- 4. The CTRL-P key combination used to send the screen output to
- printer does not check to see if the printer is on-line. This can
- cause the machine to hang.
-
- 5. The FPU CMN and CMNE instructions will not automatically do complement
- translation. This is a very minor limitation which I will be looking
- into in the next versions.
-
- 6. The 'search Mnemonic' in the mnemonics editor (dis-assembler) can not
- properly find any of the following instructions:
- 1. LDR|STR Rx,<address>
- 2. LDM|STM Rx,<address>
- 3. LDF|STF Fx,<address>
- 4. LDC|STC Cx,<address>
- 5. ADR Rx,<address>
- 6. ADRL Rx,<address>
- This is due to the offset address calculation required. This requires
- a different search routine. The routine is already included for the
- search of Branch instructions, future versions will extend this
- routine to include all the above instructions.
-
- 7. The search routine does not search physical RAM area if it was
- started in a logical RAM area. To search in physical RAM you simply
- start the search in the physical ram area. This is not really a bug,
- it is just how I wanted it to be. If you started the search in logical
- memory then there is no need to search in physical ram as they both
- contain the same data. However some logical ram pages can be hidden
- by other applications which you will not be able to access. Using
- the search in physical ram will then allow you to find what you are
- looking for.
-
-
-
- Future features to be incorporated in ARCTOOLS:
- ===============================================
-
- 1. Full support of all operating system disc and drive types in the
- disc editors.
-
- 2. The disc editors will support automatic switching between drives,
- so that you can switch between drives with the press of a key.
-
- 3. Full support of RISC OS 3 features.
-
- 4. Automatic labeling of modules with suitable names and adding comments
- to modules entry addresses.
-
- 5. Adding a *History command, and an improved line editor. Part of the
- line editor code is already used in ARCTOOLS.
-
- 6. *Dlock command will have options to lock only specified drives.
-
- 7. Many additional options will be added to the Commands Menu.
-
- 8. Improved machine index computation to cover memory, processor and
- drives tests.
-
- 9. Neat ways of entering and exiting ARCTOOLS editors from desktop.
-
- 10. Add a new *command to append labels files to existing labels in
- memory.
-
- 11. Add a printer on-line check.
-
- 12. Add a facility to allow entering hex numbers in the WORD editors
- using a normal input routine.
-
- 13. Allow the size of ARCTOOLS buffers used for storing tables to be
- specified by the user.
-
- 14. Multiple wildcards will be allowed in the memory and disc string
- search routines.
-
- 15. The *System command will be extended to show other system related
- parameters.
-
- 16. Assembly and disassembly of ARM 6xx processors instructions.
-
-
-
-
-
- Good Luck and Happy Programming.
