nadger
/nad'jr/ [Great Britain] To modify software or hardware in a hidden manner, generally so that it conforms better to some format.
For instance, an assembly code string printing subroutine that takes its string argument from the instruction stream would be called like this:
jsr print:"Hello world"
The print routine would use the saved instruction pointer (its return address) to find its argument and would have to "nadger" it so that the processor returns to the instruction after the string.
