If I understand you correctly, that might work provided that I already
have columns of longitude data, i.e. equally or non-equally spaced
coordinates (but lying on the same longitude!).

This is not, what I meant by "irregular gridding". My data points are
scattered and have all different latitude and longitude values.

The automatic gridding of the old CONTOUR procedure in combination with
the "/IRREGULAR" keyword does what I need. The question now is what is
different between the CONTOUR procedure and the CONTOUR function?

Thanks and regards

Karlo
