I have an ascii file, with two columns. The first has Latitude and the second has longtitude. Also I have one point (lets call it "MYPOINT") with spesific latitde and longtitude. I would like with the base of MYPOINT to find all the point in the radious/cirle distance of 20km (For example from the 100 points, the points that are located at a radial distance of 20m from the MYPOINT.
Which functions should I use?

Generate the points that make up the circle around myPoint, then use the inpolygon function to identify the points that are within the circle.

I know nothing about your script, and inpolygon now nothing about units. Look at the examples in the linked page for inpolygon and adapt to work with your data.
