EXHELP
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.

BCPL CALCULATIONS PACKAGE EXAMPLES
==================================
This file describes the example
programs provided with the BCPL
Calculations Package. All programs
are provided in both source and
CINTCODE form. Users are encouraged to
modify the source provided to alter or
extend the programs.
EXFLC & EXFXC
=============
These two programs use the floating
point (EXFLC) and fixed point (EXFXC)
procedures to simulate a pocket
calculator. Calculations are entered
in they same way as they are on a
calculator - thus to add 1.5 to 3.6
enter '1.5+3.6='. Note that RETURN may
be used instead of '=', ';' instead of
'+' and ':' instead of '*'.
The function keys are used to provide
mathematical functions such as sine and
square root. In the case of EXFLC
function key 0 toggles between two
alternate sets of uses for function
keys 1 to 9.
The source is contained in 7 files:
EXCLHDR is a header file containing
global and manifest
declarations.
EXCL1B contains START and various
utility procedures common to
both programs.
EXCL2B contains other procedures
common to both programs.
EXCLFLB contains procedures to handle
the display which are specific
to EXFLC.
EXCLNLB contains procedures to handle
the function keys which are
specific to EXFLC.
EXCLFXB contains procedures to handle
the display which are specific
to EXFXC.
EXCLNXB contains procedures to handle
the function keys which are
specific to EXFXC.
To amend EXFLC:
(1) Edit the source file(s).
(2) Compile EXCL1B, EXCL2B, EXCLNLB and
EXCLFLB. Note that the 'MAX'
option must be used when compiling
EXCL1B and EXCL2B (e.g. BCPL EXCL1B
EXCL1 MAX).
(3) JOINCIN the four CINTCODE files
from the compilations with FLARITH,
FLIO, FLTRIG and FLEXP to a
temporary file.
(4) Run NEEDCIN on the temporary file
with library file LIB to produce
EXFLC.
To amend EXFXC:
(1) Edit the source file(s).
(2) Compile EXCL1B, EXCL2B, EXCLNXB and
EXCLFXB. Note that the 'MAX'
option must be used when compiling
EXCL1B and EXCL2B (e.g. BCPL EXCL1B
EXCL1 MAX).
(3) JOINCIN the four CINTCODE files
from the compilations with FXARITH,
FXIO and FXEXP to a temporary file.
(4) Run NEEDCIN on the temporary file
with library file LIB to produce
EXFXC.
EXSPIR
======
This program uses the fast integer
routines to draw a spiral. It is based
on the program 'SPIRAL1' in 'Creative
Graphics on the BBC Microcomputer' by J
Cownie published by Acornsoft Ltd.
The source is in file EXSPIRB. If the
source is changed it should be
recompiled then JOINCIN used to join it
with INTCALC and finally NEEDCIN used
to extract the procedures needed from
LIB.
