It depends on what the func does in addition to the echo, and in
particular on whether it returns a value.
- This function
func Hi()
echomesg "hi"
endfunc
adds the message to Vim's message list so you can recall it with
:messages
- That one:
func Hello()
return "Hello"
endif
can be called with
:echo Hello()
- Then this one
func HowDoYouDo()
let g:Howdy = "How do you do?"
echo g:Howdy
endfunc
saves its message in a global variable so you can recall it at any point
after the function returns.
Best regards,
Tony.
