The Graph unit in Borland Pascal offers a great variety of procedures for dealing with the graphics screen. In this section we’ll illustrate some of them, starting with procedures that control how text is written to the graphics screen. The default font is a bit mapped font that does not magnify gracefully. Borland Pascal provides four other “stroked” fonts that do magnify very nicely. The following program demos these, and procedures that govern how text will be placed on the screen:SetTextStyle and SetTextJustify. The font files “*.chr” must be on line for the program to run properly. If a graphics program cannot find a font, it doesn’t crash, but simply uses the default font instead.
