In an application I'm analyzing, there's a global variable whose purpose/role in the program is known to me. I'd like to rename it, but for some reason I cannot.
The assembly code:
.text:00537E90 mov edx, ds:1C968D8h
.text:00537E96 mov [eax], edx
.text:00537E98 mov ds:1C968D8h, eax
If I position the cursor on the address (ds:1C968D8h
) and try to jump (using Enter), IDA will complain Command "JumpEnter" failed
. Attempting to rename it with the N hotkey will cause IDA to place a label at that address rather than rename the variable as intended.
While I'm doing this for educational purposes, this is a proprietary application, so I don't have the source code.
I've checked Chris Eagle's "The IDA Pro Book", but there seems to be nothing on the subject in there.
Help is greatly appreciated.
