osascript untitled applescript

[openbox]

what would be the way to osascript a untitled applscript??

I'm expecting something:
-e `"some code to refer to the untitled in the active scripteditor"'
or even better:
a pathway to the untitled script ...


would like to do this without saving the script, without typing too much in the terminal shell:
tell application "Finder"
choose file
set file1 to result
open file1
say "file opened" using "victoria"
end tell


...as a novice to this, I enjoy being entertained by applications communicating in any way.
appreciate and respect the time and effort by those dedicated to "the codes" and willing to help "novices like me" to get some relaxation from playing with a computer.

best regards,
openbox
