nadger
/nad'jr/ [Great Britain] Of software or hardware (not people), to twiddle some
object in a hidden manner, generally so that it conforms better to some format.
For instance, string printing routines on 8-bit processors often take the string
text from the instruction stream, thus a print call looks like
jsr print:"Hello world"
The print routine has to "nadger" the saved instruction pointer so that
the processor doesn't try to execute the text as
instructions when the subroutine returns.
