/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 likejsr 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.[Jargon File]
