what part of the program he is doing, and to date and time stamp that particular
'edition'.

'transmitted' to the aerial of a standard TV set.
ROM

Routine
A part of the program that performs a 'routine' task. A 'sub' program that resides
either within a main program, or may exist as a separate module for incorporation
into a variety of applications programs. e.g. A program to derive a 12 hour display
from the system's clock may be considered as a routine.
