nadger
/nad'jr/ [Great Britain] v. 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.
