Commodore MPS 1200 - PROPORTIONAL SPACING

A step forward in readability and aesthetics
comes with proportional printing where the
width each printed character occupies is
proportional to its shape.
A step forward in readability and aesthetics
comes with proportional printing where the
width each printed character occupies is
proportional to its shape.
Proportional characters are always printed in emphasized print and
are
compatible with all of the styles and widths we have discussed
so far: draft, neat letter quality, expanded, compressed, elite and
pica.
By changing the width (say, from pica to elite), you change
the overall width, but the printing will be the same as either regular
pica
or regular elite.
Using the previous program, add the line below to make every-
thing print with proportional characters. Compare the results to
your earlier printout; they will be similar, but noticeably different.

If you think we've discussed character print width just about
enough, bear with us for one more variation! In addition to chang-
ing the width of the actual printed characters, you can also vary the
space between the characters. This feature can be used in creating
fancy justified text or if you just want the print to appear "looser."
The command for proportional spacing is, appropriately enough,
ESC (space). Following the space is the number of additional print
columns (or dots) that you would like to place between each
character. To specify this number, you must usc the chr$ function;
you cannot use a statement like PRINT#1,chr$(27)" 9" and expect
to add 9 dots between characters.
