But I need to get the content of some local vars - I couldn't find a solution for about 4 hours. I tried to use VC++ style e.g. mov eax, [asm_var] - didn't work. I wrote an extra procedure and used "%0", "%1" to get the parameters - didn't work. I tried to use TASM and link the object - cygwin couldn't read it. Finally used FreePascal (based on gcc) - produced compilable asm code but it couldn't find the reference. Then I tried to get the address by calculating it with the help of %ebp - always got access violation errors. I'm new to asm so I don't know what this "=&a" (var) means, to - well to assign a var to a register it also didn't work. Is it only for results? Is there any good documentation for cygwin to download in which something like this is explained? For gnu-c there was always such an info tool. Is there anything similar for cygwin? An example prog for my problem: int main() { int a = 1; a = 1; __asm ( " mov eax, [a] ; " // or " mov ebx, a ; " // or " mov %eax, %a ; " // or " mov %eax, %0 ; " // if in an extra procedure " mov %eax, %h0 ; " // or " mov %eax, (8)%ebp ; " JUST ISN'T WORKING ... ) return 0; } Thank you. -- Leonhard ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com -- Want to unsubscribe from this list?
