+for whatever changes you wish to make, and be B to check your
+code in Netscape 4. This feature in Netscape 4 is B powerful;
+it's adequate for updating a one-line status display, but little more.
+This script will set the space to 100% width, so you only need to
+worry about height in Netscape 4.
