I think I found a possible error using the
"pca" command. Please take a look at the
following code:

open australia.gdt

open australia.gdt
pca PAU PUS E --save[1]
# It saves only the first component

open australia.gdt
pca PAU PUS E --save[2]

You should actually be getting an error message for this (I'll
fix that when I can). The syntax is supposed to be
pca PAU PUS E --save=1
pca PAU PUS E --save=2
and so on. The "[" and "]" in the help for pca are just
indicating an optional addition, and they should not be typed;
but the equals sign is required if a number is given.
In addition you're misreading the intended effect of --save=n.
Here's the help text: "If you provide a value for n with this
option then the most important n components are saved." This
means that --save=2 will save the first two components, not
just the second one.
