The right edge of the text on consecutive lines is adjusted to a selected
width of W picas (1 inch=12 picas) by the control word - [trim(W)] .
PRINT never changes division of text into lines. This must be done by
the user by TRIM operations before printing.
On variable pitch fonts (Times, Helvetica etc.) the typical form of
TRIM (see TRIM? for other forms) is
TRIM3 L1,L2,C,<font_type> 
where L1-L2 are lines to be adjusted, C is the selected width and 'P'
means proportional trimming. The last parameter <font_type> is one of
the alternatives
  P3 Times
  P4 Swiss (Helvetica)
  P5 Avant Garde                These fonts are defined in PSFONTS.DV2
  P6 Bookman
  P7 New Century Schoolbook
  P8 Palatino
  P9 Zapf Chancery

The proper C value depends simultaneously on the final printing width W
(in picas) and font size S (in points) by the formula C=12*W/S.
Of course, if a line consists of text in different font sizes,
individual editing might be needed. In normal text no extra adjustment
is necessary. For example, in case - [Times(10)][trim(50)] (i.e. S=10,
W=50) a good value for TRIM is C=12*50/10=60.

To change the width, use another - [trim()] and to abandon the right
edge alignment, use - [trim(0)]. Any line can be temporarily freed from
adjustment by putting 'U' in the control column.

The simplest way to adjust lines in proportional pitch is to use the
sucro /TRIMP.
