That would figure, me being an old IBM-head, starting out with PL1,
which sort of grew out of fortran...

Oh go on then. Send me an e-mail thingy then, and I'll arrange something.

 

I'm flying down to Gatwick tonight and then driving to Hastings, staying
there tonight and tomorrow night and driving back up to Gatwick on Wednesday
afternoon.

I didn't bother e-mailing you because there's a couple of other blokes with
me, so I suppose I'd better be sociable.

That's interpretation and storage. Makes no difference to the
representation in hex.

 

OK Try
0,1,2,3,4,5,6,7,8,9,A, B, C, D
0,1,2,3,4,5,6,7,8,9,10,11,12,13

E, F, 10,11,12,..20,21,22,..,90
14,15,16,17,18,..32,33,34,..,144

91,.. 99,.. 9F, A0
145,..153,..159,160

You see in hex 20 is 2 16s = 32
as in dec 20 is 2 10s = 20
so in hex 22 is 2 16s + 2 1s = 34
and FF is 15 16s + 15 1s = 255

Even the IBM mainframes I was programming in the early 90's used the 0x
notation..

As has just about every unix box I have owned since.

Early 90s? Pfah, newbie.

 

Well - since we are being snobbish - my first program I wrote (at the
age of 12) in 1977. On a NASCOM 1. In Z80 hand-assembled hex.

Et tu?[1]

Not so. Nearly all computers have always used binary. However, depending
on the design of the computer it is often convenient for us to work with
either octal or hexadecimal, both of which are used to this day.

You need to use a power of two[1]; hex and octal are used because they're
relatively close to 10, so easy for us to deal with.

[1] One hexadecimal digit translates directly to four binary digits, which
makes translation very simple and also means that you can perform logical
operations on hexadecimal numbers without having to translate them to
binary and back again, which would be necessary with decimal.

 

But of course. Des told me so. And he wouldn't lie to us now would he?

Pah. Newbie

I was playing 'games' by that point (if guiding an ACSII block between
other ACSII blocks qualifies as a game..)

Mind you - it wasn't until I get my first BBC Model B that I discovered
the delights of BBS's and dial-up comms. And that was on a 1200/75 baud
modem with no dial capability..
