4D can read fixed length data

hard to believe after years of years of parsing text myself to get the records into my database, I finally discovered, there is an option to import fixedlength data into 4D by using the build in import-editor:

If only the interface of the import-editor wouldn’t scramble already selected parameters much to often or preloading a saved import-station would really load well before importing by code.
