In IDA Pro, how can I modify a instruction?
such as:

_text:00413B96 mov [ebp+var_C], 7648B98Eh

I want to modify the above instruction to:

_text:00413B96 mov [ebp+var_C], 88888888h

You can enable the patch-tools in the edit menu by having the following line in your idagui.cfg file:

DISPLAY_PATCH_SUBMENU = YES
