I used BASIC on C64 and ZX81 but soon changed to ASM and even this 
didn't satisfy my needs for freedom, so I started with machine code.
My background is EE and Math, but HLL programming wasn't part of 
education at this time. Of course we heared about Cobol, Fortran 
and the like, but learned that this HLLs are made for non_technical 
people and we learned much more about Lord Logic.

I see a 'static variable' as one kept in memory until terminated. 
'non-volatile' could be the other word for it ?

There aren't any symbolic names in my code, because there is also 
no text-based source.

I remember Roundabouts when I was in UK for vacation-update :)

My code- and data-labels are just hex-figures and mean their address.
