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.

M.J.RAWLINGS 31-12-86 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 f7 0.4536 lbs TO kgs f8 0.0703 lbs/sq in TO kgs/sq cm f9 0.74531 bhp To kw M.J.RAWLINGS 31-12-86 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"
