Hallo,
the ascci file format *.ASC should be like the following example
6.745680,51.270170,"16695|Düsseldorf|A44"
6.839955,51.227561,"17512|Düsseldorf|Dreherstraße"
6.684050,51.006130,"5545|Rheidt|B477-Düsseldorfer Straße"
where the first is the longitude, then latitude, then "Description"
The Description must be in double quotes and the latitude and logitude must be with '.' not ',' because by importing this data a conversion is made.
Hope that helps
