Bool

[boriel]

thanks, what is the value of 'address'?
on the line that starts with:poke address

Any address or pointer...

Code:

poke @booltable+1,(peek booltable+1)|(switch4<<4) 'use second bytes 4 th bit
end

booltable:
asm
  defb 0,0,0,0,0,0,0,0  ;8 bytes=64 bool bits
end asm

Boriel also wanted to add SETBIT, RESETBIT and TESTBIT commands, but existing binary operations are good enough because you can manipulate multiple bits at once.

In fact, FreeBASIC implements them as Macros. You can also implement them as macros using #define as explained above (I've updated ZX Basic operator priorities to reflect FreeBasic's ones, but you can always enforce priorities using parenthesis; this won't affect performance).
