Purpose

The X Window System supports a range of line widths. Because some X Window System servers draw wide lines at a slow rate, you can use the Zero Width Lines (ZWL) to tell GDDMXD/MVS to draw all lines using 0-width lines. The X Window System server uses the fastest process to draw the lines. The resulting line might not be exactly the same as if it had been drawn as a wide line.

Parameters

N

Directs GDDMXD/MVS not to use 0-width lines for all drawing. This is the default.

Y

Directs GDDMXD/MVS to use 0-width lines for all drawing.
