You can use "Result" variables that are predefined in BAS. There are 9 of them.
If you need more you can use filesystem actions and create TXT or CSV files
to store any number you need. Similar to that you can use database for such
tasks too.
You can fill in the whole form with one action if you
use <TAB> in "Text to type" input field. It acts as you
actually pressed TAB button on keyboard. You can even
use <RETURN> at the end of form filling to submit form
data - it acts as if you pressed ENTER button on keyboard
to submit the whole form data.
