Variable actions are expected to be called with labels in
front of them. Example, "L2 FSET"

About that "1 -": z80 relative jumps record "e-2", that is,
the offset that *counts the 2 bytes of the jump itself*.
Because we set the label *after* the jump OP1 itself, that's 1
byte that is taken care of. We still need to adjust by another
byte before writing the offset.

z80a: add BIN( parameter Will be useful for assembling binaries for the TRS-80 which can't start at addr 0. 2020-04-28 05:04:37 +10:00			`Variable actions are expected to be called with labels in`

z80a: add BREAK, instruction This allows us to remove a lot of labels usage in boot code. This commit has no effect on forth.bin. 2020-05-17 11:02:50 +10:00
