[gradsusr] How to get four variables to a single output file...????

[Jennifer Adams]

This question and similar variants comes up so often, I have finally written a documentation page about importing/exporting ASCII data. 
Please see http://iges.org/grads/gadoc/ascii.html. This page is linked to from the headings "ASCII data" and "text data" in the documentation index. At the moment, the examples are all based on gridded data. The fprintf.gs script in the opengrads cookbook is quite similar to example #2 in the doc page. The third example takes it a bit further and shows you how to do what you are asking here.
