How can I find the distance between my first two digitized points in Surfer Scripter?

This article contains a sample script for calculating the distance between the first two digitized points.

To run this script:

1. Copy the script below, or download the attached BAS file: DistanceCalc.BAS
2. In a Windows Explorer window, navigate to C:\Program Files\Golden Software\Surfer 16\Scripter.
3. Double click on Scripter.exe to launch Scripter.
4. Press Ctrl+A to select all of the existing lines then press Delete.
5. If you copied this script, press Ctrl+V to paste it into Scripter. If you downloaded it, click File | Open, select the BAS file from your downloads directory, and click Open.
6. Click Script | Run to run the script.
