Don't worry if some directives don't make sense yet; they will be covered soon. Also, take
special notice of the SEGMENT directive.
3.4
Segmentation
Segments are very important. You have to understand segments before you can use the
assembler. Take the time to understand them now and you'll save yourself a lot of puzzling
later.
Segmentation is a way of 'naming' areas of your code and making sure that the linker collates
areas of the same name together in the same memory area, whatever the order of the
segments in the object files. Up to 128 different segments may be defined in each module.
The segment directive itself has four arguments, separated by spaces:
[<name>]
SEGMENT [<align>] [<combine>] '<class>' [cod]
For example:
segment word at: FFFC 'code'
WORD start
end
FILE1:
st7/
BYTES
segment byte at: 80-FF ‘RAM0’
counter.b
ds.b
; loop counter
address.b
ds.w
; address storage
ds.b 15
; stack allocation
stack
ds.b
; stack grows downward
segment byte at: E000-FFFF ‘eprom’
ld A,#stack
ld S,A
; init stack pointer
end
