Why doesn't it work? Does the compiler tell you the program can't be
compiled? Check if a0 is even or odd, because if you try to store d1.w to
a0, this must not be an odd address, since this leads to an address error!
If this is not the error, check another thing:
I suppose you want to add the address of t_stat to d0! Yes? If so, remove
the parentheses from the code line.
add.l #(t_stat),d0 -> add.l #t_stat,d0
If this still doesn't work, there's (obviously ;-)) something else!
I suppose 'move.w d1(a0)' from above is a typo, the correct syntax is
'move.w d1,(a0)'! This could also be the reason why it doesn't work, but I
assume it's not THE reason...
If you can't fix the problem, mail me at mike_emk@hotmail.com and tell why
exactly this doesn't work, and I'll try to help you, but till then, remove
the parentheses, I'm sure this is the bug!
See ya,
