Hi all,
In 6.3, as in latest versions, you can use : INPUT FROM xxxx.txt, IMPORT field1 field2. (but without using DELIMITER), INPUT THROUGH (unix).
If you have text files with a delimiter other than space (like ";" or "," in CSV), you can use quoter utility ($DLC/bin/quoter) to format your file (add quotes, change delimiter...).
It's still distributed and documented (I can't add the link).
(apologizes if I made mistakes, it's my first post).
