Dear Gretl Team,

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

<hansl>
open australia.gdt
pca PAU PUS E --save-all
# It saves all the components

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

clear
open australia.gdt
pca PAU PUS E --save[2]
# It was supposed to save only the second
# component, but Gretl saves only the first

clear
open australia.gdt
pca PAU PUS E --save[3]
# It was supposed to save only the third
# component, but Gretl saves only the first
<hansl>

According to the Gretl's Help, in respect to
the option "--save[=n]":

"If you provide a value for n with this option
then the most important n components are
saved."

Additionally, inside a BIG loop I am building,
the order of the options "--save[1]" and "--quiet"
is changing the behavior of Gretl.

Using the format "pca ... --save[1] --quiet"
doesn't suppress the printing of the PCA
results. To suppress, I need to use
"pca ... --quiet --save[1]".

Best regards,
Henrique Andrade
