Bashforth - How to use the "system" and "system2" words?

The "doc system" command returns:
system ( a n1 -- n2 )
shell, string is command + arguments. returns exit code

and "doc system2" :
system2 ( a1 n1 a2 n2 -- n3 )
shell, append a2 n2 as arguments to command a1 n1, returns exit code

Can I use this words to do some data manipulation on bashforth and send
to bash to use in other scripts? Is this the idea of these commands?

Thanks!

Well, this is what i've found:
: teste s" ls -lh " system ;
The test word will execute the list command in the bashforth!
