Using open() writeline() close() or redirectoutput() can lock a file open. This is not a problem if only 1 user at a time will be writting to the file.

But if you are wanting to have many people write to a file, then using a shelled redirected ">>" ECHO or the INI type output of writeprofilestring() would be the way to go.

also, using the open() command will load the entire document into memory, if the document is small, there will be very little speed difference, but if it is a large file (500m to a gig) then the

ECHO "stuff" >> largefile.txt

would be faster.
