Linearity of reading seems at work here: proc_body, in body
Greetings, appears after the line that says "Hello is
separate". Therefore, when that line is "evaluated", there
is no procedure proc_body (yet).
To resolve the issue, either put a specification of
procedure proc_body before "... Hello is separate", or put
the latter line after proc_body's definition.
