nadger /nad'jr/ v.
[UK, from rude slang noun
`nadgers' for testicles; compare American & British `bollixed']
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
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. See adger.
