Margin
procedure Offsets text within a series of commands, relative to the original top left
position of the object. Margin also sets the horizontal position to be
used when crlf commands are encountered. All text-rendering
functions that make use of margins use this setting.
Show
ShowCenter
ShowRight
procedure These three commands are used to display simple text on the
document. They are identical in all aspects, except in the way they
behave relative to the current margin settings: show uses the margin as
a starting point to extend the string to the right; showright uses the
margin as the ending point of the string; and showcenter extends the
string equally on both sides of the margin.
ShowLeftRight
procedure Displays a string of characters, in inches, using a specified width.
