This is certainly true in graphics mode, but there are systems in
which this is not the case; an underline is provided as part of the
standard text attributes. In this case, setting the text colour to
blue (1) and the background to white (15) had the effect of producing
an underline. Whether this would work on all (nongraphic) monitors
of this type, I have no idea. But if your monitor/card DOES display
underlined text, getting it is simply a matter of setting the
appropriate text attribute bit, which in TURBO Pascal is a matter of
using the TEXTCOLOR and TEXTBACKGROUND routines.
