Spacing Option
You can use the SET SPACING command to control how many lines
TFORM places between text lines.
SET SPACING num
This command tells TFORM to output ( num -1) blank lines after each
line of text. So SET SPACING 1 produces 0 blank lines between
text lines (single spacing), SET SPACING 2 gives one blank line
(double spacing), and so on. Spacing can be done in half-line
increments, too SET SPACING 1.5 yields “line-and-a-half”
spacing, and so on. The physical interline space depends on the
current vertical pitch.
The minimum usable value is 1 (TFORM treats any value less than
1 as if it were 1); the maximum is 32. The value must be unsigned
and must be in whole- or half-line increments. The default is 1.
SET SPACING FIXED
When you specify SET SPACING with the keyword FIXED (with or
without a spacing value), you tell TFORM to maintain the specified
spacing at all times. Normally, TFORM adds an extra half line of
space before or after the current line for each level of superscript or
subscript (they can be nested) that the line contains. TFORM has no
way of knowing—especially if you are using proportional
spacing—if the superscript or subscript will overlap any characters
on the adjacent line. If you tell TFORM not to do that with the
FIXED parameter, preventing overlap of superscripts and
subscripts is your responsibility.
SET SPACING
SET SPACING with no value (with or without the keyword FIXED)
resets the interline spacing to its default. The default is SET
SPACING 1.
