hi guys
in want to avoid access violation by handling it not to write many lines of compare.
i.e : I want to get a pointer mov tax,[rcx] sometimes it contains a pointer and sometimes it doesn't. now I want to handle this exception like when hit , go to label X.

Code:

mov rax,[rcx]
jmp noerror
{$except}
//error happened

noerror:
//no error happened
