Re: Wikipedia articles on Econet and DFS [citation needed]

Barson also had their own version of the L3 file server: capture86.png I'm not sure that's "their own version", the file server code has a block of nulls or blanks or a message such as "Pre-release IV.05" after the startup message which presumably can be overwritten with a customised startup message.

Re: Wikipedia articles on Econet and DFS [citation needed]

However it doesn't ring true to me that Acorn had them effectively writing the DFS and NFS software for the Beeb. Both filing systems had been around a while in earlier Acorns, all of which used the 6502, by the time of the BBC micro, as had the disc and net interfaces, so it was hardly a question ...

Programming Tips: Testing modified Electron editing keys

Chatting with Dave H earlier reminded me of a programming tip. On the Electron the editing keys are shared with character keys, so you normally can't detect modified editing keys (eg Shift+Dowm, Ctrl+Right, etc) in the same way as on other computers by using *FX4,1 or *FX4,2. However, if your progra...

Re: TARDIS - Text And Relative Dimensions In Screen

And using "proper" OS calls, OSBYTE 160 reads the VDU variables, 8/9/10/11 are the text window in the same order as VDU 28,left,bottom,right,top. If your text window fills the whole screen so that you know that the top-left is (0,0), then as OSBYTE 160 returns two adjacent VDU variables, OSBYTE 160,...

Re: Regex for UK Telephone Numbers

(Edit: oops, pipped in the post.) I remember when Bristol changed - perhaps from 0272 with six digits to 0117 with seven digits, everyone got a 9 on the front of their number, and yet quite a few public signs and printed materials mistakenly wrote 01179 as the prefix. Similarly in Sheffield, though...

Re: Regex for UK Telephone Numbers

There does seem to be a lot of inconsistency with regard to how to format the new number. I've seen a multitude of ways, including (02392) 123456, 023 92 123456, 02392 123 456, and 023 9212 3456 (which is the preferred way I am led to believe).

You basically want a "copyleft" license. That term really annoys me as 'left' is *not* the opposite of that meaning of 'right'.
