axlGetAttachment adds a NUL character at the end of the file

Hi all,
I have a problem with the axlGetAttachment function.
This is what I do...

a=axlGetAttachment("testFile.txt" 'file)
renameFile(a->data "MyTestFile.txt")        - this is to get the file saved into the working folder
p_myFile = infile("MyTestFile.txt") 
while(_text=lineread(p_myFile )
     println(_text)
); end while
close(p_myFile)

The problem is, when the attachement if fetched back from the database, it adds a NUL character at the end of the file.
In notepad++, it shows as a NUL and in Wordpad it shows as a blankspace
When the script above is run, it halts with an error:-

(("REMARKS_AR1" "testing this out,,"))
E-
E- SYNTAX ERROR found at line 6 column 1 of file MyTestFile.txt
E- *Error* lineread/read: syntax error encountered in input
ERROR

Any idea on how to handle this?

Thanks
