Yes, you can, but remember that URL is both a keyword and a function, and
although it can work without parentheses for some file operations (like
"into"), it doesn't work when using "after" or "before" without using
parentheses, and can be touchy at other times.
So I think we've been "getting away" with saying:
put data into url "file:c:/my documents/test.txt"
when we really should be saying:
put data into url("file:c:/my documents/text.txt")
I'm afraid that's not right, Ken. URL isn't a function, and while
your example will work, Rev might not always let you get away with
leaving out the space after "URL".
The reason you need to use parentheses in statements like
get URL ("file:" & myURL)
is that URL resolution comes before "&" when resolving expressions.
(Ken can stop reading here, since he's an expert and knows what that
implies, but for everyone else: ;-)
If you write something like
get URL "file:" & myURL
the engine thinks you mean "get URL 'file:', then concatenate it to
the variable 'myURL'". Since "file:" by itself isn't a valid URL, you
don't get what you want.
Adding the parentheses forces the engine to do the concatenation
first, so you get the URL you're seeking. But in this case, the
parentheses have nothing to do with a function call; they're there to
straighten out the order in which the engine does the operations to
get the final value of the expression, 'URL "file:" & myURL'.
