Figure 2. 20. Printout of the DPAT Example

In this program, the DPAT command selects the dash pattern with which the line is

stroked.

Predefined dash patterns are selected by specifying values from 1 to 10 for pattern-num-

ber. (A value of 1 specifies solid lines.) User-defined patterns can be selected by specify-

ing values from 11 to 20. The next section explains how to use the SDP (Store Dash

Pattern) command to define your own dash patterns. Specifying an undefined user pat-

tern number results in solid black lines.

User Defined Dash Patterns

Using the SDP command, you can define your own dashed patterns for use in stroking

lines, arcs, and curves. See the following example:

!R! RES;

UNIT P;

SDP 11, 2, 2, 5, 2;
