BCPL/armlib/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.

File contents
24 Feb 88 MCLib 1.6 There was a small mistake in the Error Handler in 1.5, causing instant collapse if an OS Error happened. Also, there was a mistake in the SWI procedure, whereby the branch to the SWI planted on the stack could be off by a few (result: chaos). 22 Feb 88 Map 1.5 Definition of argument to Abort changed: it is now an Arthur error code rather than a small integer. 22 Feb 88 IOLib 1.8 Implementation of Date and TimeOfDay changed. As a result, the procedures BinaryTime (to get current time as 5-byte quantity, as for timestamps) and ExplodeBinaryTime now exist. BinaryTime, Date and Time all now work properly for Arthur. WriteF now has a %f format descriptor, for Reals. Fault (called on IO system faults) now no longer attempts to call Abort if it isn't defined. As a result of improvements to mclib 1.5, faults on file output are now no longer concealed. 22 Feb 88 MCLib 1.5 The event handling mechanism is now capable of handling events numbered above 9 Escape handling now works under Arthur Abort handlers are installed in the approved way, so that BCPL programs may be run under DBug. OSBPut reports errors correctly The SWI function has been added The OSByte2 function has been added.
