[Solved] Writing data to text file

Hi guys,
I found two different ways of writing data into text files. Both methods work for me, so I am wondering what may be the difference between them? Any advantages or disadvantages?
1.
Code: Select all
put specialfolderpath("Home") & "/test" into theFile
open file theFile for write
write "hello" to file theFile
close file theFile
Code: Select all
put "file:" & specialfolderpath("Home") & "/test" into theFile
put "hello" into line 1 of URL(theFile)

The url syntax is shorter!
1. The "open file..." syntax is better suited when dealing with LARGE files like server log file with hundreds of MB.
2. The url syntax will read the complete content of the file into RAM do what you want it to and then write it back to disk. Since nowadays we ususally have LOTS of ram installed on our machines, most of the time this will work fine.

To write a file in one pass, the URL is method is simpler to write. If you need to do multiple writes, seeks, or other operations beyond a one-pass write, the "open file" and "close file" commands are what you'd use for that flexibility.

Yes, and that.
