But Woz came down, and I got to interact with him and it was really fun
because he was working on installing these 16-sector disk driver
routines, and he'd go 'type type type type type' -- and he didn't type
in assembly language and have it assembled. No, he'd type in 6502
machine code. Hex. -- He'd type in hex, and then, you know, watching
him type and he'd go 'type type type' -- pause -- 'type type type type',
and when he finished I asked him what was the pause? And he said
"forward branch, seven instructions, I had to compute the offset before
I continued". So, he didn't back-patch the offset, he actually looked
at what he was going to be typing, knew how many bytes it would take...
he was brilliant.
- Bill Atkinson, quoted in
a conversation about Pascal on the Apple II, specifically about when he was given just one week to code
something to convince Jobs that Pascal was a good idea:

I'm reminded of a really great interview with Bill Atkinson where he describes (among many other things) how he initially brought Pascal to Apple and the Apple II.
