Apple][e/PD/BOB/ARMBOB/doc/History
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.

Changes:
# Altered syntax from
f(x, .. ;a, .. ) { ... }
to
f(x, .. ){ local a, .. ; .... }
# Implemented input() using OS_ReadLine.
# Implemented sysvar() using OS_ReadVarVal.
# Implemented switch-block
switch (<expression>)
{
case <expression> : <statement> [ break; ]
........................................
[ default : <statement> [ break; ] ]
}
The only difference from standard C is that a single statement
follows the colon (or a block enclosed in braces).
This required two new opcodes for the virtual-machine:
OP_DUP and OP_DROP.
# Altered action of comparison operators to allow comparisons between
strings as well as integers.
# Introduced 'repeat' as a variant to 'do' with 'until <test> ;' as
an alternative to 'while <test> ;'.
# Implemented rnd() and seed() for random integers.
# Implemented quit() to terminate program with a message string.
# Altered system() to oscli().
# Allow @,$ and ` in identifiers.
# Implement swi(n,regs) to call SWI number n, with registers in
vector regs (regs = newvector(8)).
# Implement @(s) for address of string s, and $(adr) to get the
string at adr.
# Allow positive hexadecimal numbers with a & prefix. Lower case
a,b,c,d,e,f are used for 10,11,12,13,14,15.
# Added built-in constants, TRUE, FALSE, names for the types, and
SWI numbers.
# Removed bug in switch/case. Added built-in val() to convert
strings to integers.
# Modify swi to take string arguments.
# Implement peek and poke for reading and writing words to buffers.
# Improve switch/case structure so as to conform completely with
C syntax.
# Change syntax of peek and poke, so that `(), �(), $() peek bytes,
words and strings respectively, and ``(), ��(), $$() poke.
# Added the
in buffer put { item1; ..... itemn; }
construction, for initializing window/sprite/menu/message blocks.
This requires the addition of two more opcodes, OP_ADR, OP_PUTNEXT.
# Added an internal variable w_task to hold task handle. Implemented
wimp_report(s),
wimp_close_down(),
wimp_init(version, name, mesg_list).
# Modified Bobint.c to give an error message if a function is not
found. Altered the flag decoding in bob.c to be able to trace and
debug projects.
# Cured another bug in switch statement.
<- version 1.01 02/03/94
# Cured bug in h.string.string
# Misprint found in compiler source:
changed an instance of SHL_EQ to SHR_EQ. >>= now works.
<- version 1.02 06/06/94
# Added throwback for compiler errors. 25/06/94
# Added the start_task(command) function. This works whether
from a BobFile or a BobTask.
# Hand crafted the code for the interpreter and memory management
in assembler.
<- version 1.03 14/07/94
# Added floating point arithmetic. 28/11/94
<- version 2.0 29/11/94
# Added vector { ... } and enum { ... } constructs. 1/12/94
Used Aeby's active text for manual.
Added draw library.
Eased syntactic restrictions in project files.
<- version 2.1 25/12/94
# Some more example software from Prof.G.N.Ward:
Algorithms for square roots, matrix handling, number formatting
# Some internal changes to permit more than 32K codespace.
-quit added to Taskwindow commands.
A correction to the draw package.
<- version 2.2 25/07/96
