You can directly edit a file in AppleScript, for example:
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFDDFF;
overflow: auto;">
set someLyrics to "blah blah blah
blah blah blah"
set theFile to (path to desktop as text) & "test.txt"
set fileRef to (open for access file theFile with write permission) --fileRef is used to reference the file
write ((current date) as text) to fileRef
write return to fileRef
write someLyrics to fileRef
close access fileRef --be sure to close the file </pre>
If you want to append to an existing file, you need to write beyond the existing contents (eof=end of file):
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFDDFF;
overflow: auto;">
set someLyrics to "blah blah blah
blah blah blah"
set theFile to (path to desktop as text) & "test.txt"
set fileRef to (open for access file theFile with write permission) --fileRef is used to reference the file
write ((current date) as text) to fileRef starting at eof
write return to fileRef starting at eof
write someLyrics to fileRef starting at eof
close access fileRef --be sure to close the file </pre>
There's quite a bit more to this subject, but if you need to ask further questions I would encourage you to post these separately to get the widest audience / quickest response.
