General/CAL\INF

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

                              CALCULATOR


          The Calculator program converts the BBC/MASTER/ELECTRON into
a  talking  programmable  multi-memory  calculator,  it  combines  the
mathematical facilities of a computer  with  the  ease  of  use  of  a
calculator.  All  the commands are listed at the base of the screen in
abreviated form and are available with a single key press.  Press  <H>
to view, in turn, the other 6 help pages.

MEMORIES M0 TO M9

          To  set a memory type M1=<VALUE>, to add the last calculated
value to a memory type M0+, to subtract the last calculated value type
M0-.


DEFINABLE PROGRAMS P0 TO P9

          There are ten definable programs which can be used to set up
standard mathematical formulas. Any program can refer to  any  of  the
other programs (except itself) as well as any of the ten memories. For
example:-

                    P1=M0*P2/(M1-M3)

SAVE FACILITY

          Press  <TAB> at any time for the choice of saving or loading
all your defined programs and memories to disk or tape. Note that  the
program  checks  which  filing  system  is currently being used before
automatically  restricting  the  length  of  the  filename   used   (7
characters for disk, 10 for tape).

CONVERSION FACTORS

          The  10  standard  conversion factors available from the red
function keys are:-

               f0 25.4           ins TO mm
               f1  0.9144      yards TO metres
               f2  1.6093      miles TO kms
               f3  0.0929      sq ft TO sq metres
               f4  0.02832     cu ft TO cu metres
               f5  4.546     gallons TO litres
               f6 28.35          ozs TO grams

                              CALCULATOR
               

THE COMMANDS

          All the available commands are  listed  in  the  first  help
screen,  most  work  as  described  in  the USER GUIDE but some need a
liitle more explanation:-

          TAN, SIN and COS give results in degrees not radians  unlike
          the  normal  BBC commands, similarly putting ARC in front of
          these commands will convert back into degrees  not  radians.
          For  example SIN45 will give 0.707106781 not 0.850903524 and
          ARCSIN0.5 will give 30 not .523598775.
          
          Pressing <K> or <CTRL>+<U> will wipe a whole line of  input,
          whereas  pressing  <DELETE> will erase one digit of a number
          or one whole command at a time.
          
          <RETURN> serves as the = key,  except  when  using  %  which
          works exactly as a calculator, i.e. without needing to press
          <RETURN>.  The  other  mathematical  functions are available
          without pressing shift; <+> or <;> will produce <+>, <X>  or
          <x>  or  <*>  or <:> will give <X>, </> or <?> will give </>
          and <-> or <_> will give <->.  
          
          The calculation is rounded  up  to  the  number  of  decimal
          places  shown on the first HELP screen, this can be reset by
          pressing <@> then a number from 0 to 9. The  decimal  places
          can  be  reset  at  any time, similarly any HELP page can be
          viewed at any time, even in the  middle  of  a  calculation.
          Note that any value stored in any of the ten memories is not
          rounded  up  but is stored to the maximum accuracy available
          on the computer. Future calculations  which  call  up  these
          memory  values  will  use  the full value, whereas any value
          displayed in the centre  of  the  screen  will  be  used  as
          displayed not as remembered.
          
          If  you press <~> (<SHIFT>+<^>) immediately after the result
          of  a  calculation  has  been  displayed  then  it  will  be
          converted   to  hexadecimal.  Similarly  pressing  <Z>  will
          convert a positive result  into  negative  and  vice  versa.
          Hexadecimal  numbers  will  be  accepted in a calculation if
          preceded by <&>.
          
          Calculations can be typed as a string of  commands  complete
          with  brackets  where the order of calculation is important,
          e.g. 34*(M0-3.4)^2.  Brackets  are  not  needed  around  the
          parameters  of  any commands, e.g. TAN33 not TAN(33). Spaces
          between commands are usually not nescessary as  the  program
          has  its own built in interpreter, though if you ask for the
          impossible you will get an error message.













                                                 M.J.RAWLINGS 31-12-86
                              CALCULATOR

SPEECH

          If your machine  has  the  acorn  speech  upgrade  then  the
results of the calculation will be read back at you, together with any
error  messages  where  appropriate. The sound routine interpretes the
figures intelligently rather than merely reciting a string of numbers.
For example the result 1521.03 would be spoken as "fifteen twenty  one
point  oh three", not "one five two one point zero three". Very useful
for "head down" calculating, with no need to be constantly looking  up
at the screen.

COMPATIBILITY

          The  program  will  work  on  a BBCB/B+ with or without 6502
second processor, on a MASTER with or without TURBO  co-processor,  as
well as on an electron, without any customising. It comes in two parts
for  reasons  of space, these two halves are numbered consecutively so
that they can be combined into one listing if you have shadow ram or a
second processor / co-processor. Delete line  400  from  "Calc1"  then
SPOOL  the  listing  onto  disk,  load  "Calc2" then *EXEC the spooled
listing one:-

                    >LOAD"Calc1"
                    >DELETE400
                    >*SPOOL CALCSP
                    >LIST
                    >*SPOOL
                    >LOAD"Calc2"
                    >*EXEC CALCSP
                    >SAVE"Calc3"
