write fails

[Lynch, Jonathan]

Thanks Ken!

So, you could say:

Put tMyText after URL(tFileURL)

But, would this be just as good as opening a file for append, then
adding information to that file?

Basically, does the open/append/add method load the entire file into
memory, then add the text, then write the new text back to disk? Does
the put after URL method do that?

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")

For example, this will fail to compile:

  answer file "Get a file:"
  if it <> "" then
    put "hello" into url "file:"&it
  end if

But this compiles fine:

  answer file "Get a file:"
  if it <> "" then
    put "file:" & it into tFile
    put "hello" into url tFile
  end if

Better yet would be to use parentheses instead:

  answer file "Get a file:"
  if it <> "" then
    put "hello" into url("file:"&it)
  end if

Just my 2 cents,
