I was confused by the function of the number at the end of the following code
lcText = "This is my text"
=STRTOFILE(lcText,'TMP.txt',1)
The 1 retains what is already in the TMP.txt file so that the new text is added to what is already in the TMP.txt text.
I just discovered that using 0 instead will write the TMP.txt anew effectively erasing the existing TMP.txt
.... which is what I was after. Sorry the posting was a bit confused - many thanks for your suggestions.
