Dear Chris and J Forum:
I created a test script, encrypted ("locked") it with 3!:6, and saved the
result as a new ijs file. But when I loaded the new file, I received the
message "spelling error." So obviously I need to know how to use locked
scripts. Please, someone, explain. Thanks.
Sincerely,
Leigh

You can encrypt scripts using 3!:6.
