LT type [, pattern length [, mode ;]]
This comlmandspecifies the line pattern to be used when drawing lines
When no parameters are specified, this command selects a solid line and
saves the previous line type, pattern length and any unused portion of the
pattern. If there are parameters, a pattern is selected as follows.
Patterns are described by the length of dashes and gaps, as a percentage of
the pattern length, starting with a dash. 07crepresents a dot. Patterns and their
codes are:
code

0 (not a line, only one point)

If the pattern code is negative, from –8 to –1, the pattern corresponds to the
absolute value of the code, but the pattern is "adaptive" and its length is
adjusted (up or down) to fit one or more complete patterns.
After a solid line has been selected by specifying LT without parameters,
pattern code 99 restores the previous line pattern and any residual pattern.
LT99 is ignored when anon-solid line pattern is selected. While plotting with
a solid line pattern, the following commands clear the previous line type and
any residual pattern: AC, DF. IN, 1P,IR, IW, LA, LT, PW, RF, RO, SC, SP,
UL and WU.
The pattern length is measured as a percentage of the distance between P1
and P2 if mode = O,or in millimeters of mode = 1.
If not specified, the current values of pattern length and mode are used.
