asm code problem.

[Peter]

Something runs wrong with last OxygenBasic versions.

I have had never problems with making of dlls. But now, 24 hour on the day.
One could think, Charles don't like aliens dlls. It makes him afraid.

Hi Emil,

This will work when run directly in memory, but when compiled, it cannot work because you are writing into a code section, which is configured as read-only. To create some data space you can map to global and static variables for fixed-location storage, or local variables to stack storage or strings and bstrings for heap-allocated storage.

Interesting case

Code: [Select]

addr ecx,xx
mov [ecx] , 0x64
print hex [ecx]
end

.xx
dd  0

Peter,

I'm giving DLLs a thorough workout with ScriptBasic, PowerBasic and thinBasic interfacing. Since my last Oxygen posting (with the RTLs)  I have not come across any major problems, though a  few subtle ones,  mainly associated with complex C headers.

oh . i got it Charles , this will work okay

Code: [Select]

sub main()
addr ecx , xx
print hex [ecx]
MOV [ecx] , 100
print hex [ecx]
end sub

main
end

.xx
dd  10

but see the next one it compiled and worked okay , as you said it will resident in  read-only section!!!!!!!

Code: [Select]

addr ecx , xx
print hex [ecx]
end

.xx
dd  10

thanks ,
Emil.
