What does mean "error: code cannot be generated"?
Why it cannot be generated?
This error is occured on quite legal code. It so strange when I add a line like a db 1234 and fasm 1 shows this error.

Now I've done something like this:

Code:

org     0xF0

; . . .

if      some and 0xFF = 0
        mov     ah,some / 256
else
        mov     ax,some
end if

; . . .

if      some and 0xFF = 0
        adc     dl,al
else
        adc     dl,0
end if

align   16

some:

This simple code is compiled ok.
But more complex (with extra conditions, more code and so on) can't be compiled.

This error message means that the assembler was not able to find a stable solution within a given limit of passes. Sometimes the solution may not exist at all, and even if there was one and the number of passes was unlimited, the assembler might still not be able to find it.

You can learn more about it my article about optimistic multi-pass assembly.
