I have just discovered a bug I have introduced into dasm.
In the following code...
VALUE = $80
and #VALUE ; works OK
and #~VALUE ; fails
The problem is that ~VALUE becomes 16-bits and then we get
and #$FF7F
... which is, of course, illegal.
The quick fix is to use
and #(~VALUE)&$FF
It's ugly, but until I find some time to correct this error, please either
use an earlier version of DASM, or the above workaround. This, of course,
means the current version of DASM may not be able to compile legacy code
as-is.
Cheers
A
