It's a bit more typing but other than that relatively easy. Specifically, the statement should read:
And that's all there is to it! (I'll add, just to make sure that there is no confusion, that the "set ", the "fn=..." and the "tgz" are all on one line, they are on separate adjacent lines in the above because of the limitation of maximum line length of the display in this bulletin board.)
You can also similarly use the @Format function if you prefer.
