Okay, well it sounds like there is no real consensus on assembly.  I  
guess I'll stick with what I've got, then, which currently looks like  
this:

meta.preprocessor.directive.assembly.Asm96002: assembler directives  
(e.g. dcb: define byte-level storage)
meta.preprocessor.function.assembly.Asm96002: functions evaluated at  
assemble-time (e.g. @cvs: convert memory space)
keyword.other.opcode.assembly.Asm96002: processor instructions (e.g.  
bclr: test and clear one bit)
variable.language.register.assembly.Asm96002: internal registers and  
their sub-fields
constant.numeric.assembly.Asm96002
string.quoted.single.assembly.Asm96002
comment.line.assembly.Asm96002

Here is an example of how it looks in the Mac Classic theme:



(Aside: I couldn't find any way to copy or save text with the  
formatting preserved and had to resort to a screen dump.  I guess I'll  
have to add rtf export to my wish list, along with multi-window  
projects, split views, and print selection.)

I have yet to decide what (if anything) to do with user-defined  
symbols. Should I try to distinguish between equates (constants),  
functions, and storage variables? That could be difficult. Maybe I'll  
cop out and come up with something generic like "label" that covers  
everything.
