YP Vernier 1.1 (Learn how to read a vernier caliper)

YP Vernier is an educational program showing how to use a vernier scale to
measure length with great precision. YP Vernier simulates a vernier
caliper on the screen. Using a scroll bar, the user moves the movable jaw,
and the corresponding numerical value is displayed on the screen. The
program can also be used in "quiz mode": the movable jaw is placed at a
random position, and the user try to find the corresponding measure.

New in this version:
This new version provides two additional ways to slide the movable jaw: in
addition to the scroll bar, you can now use the arrow keys of the keyboard,
or grab the caliper with the mouse pointer.

System Requirements: MacOS 7, 8 or 9.
