I have a backup program that uses a DO WHILE loop to copy files from one drive / directory to another...

The loop is structured as follows:

<b>
nIndex = 1
DO WHILE nIndex <= ALEN( aFileList, 1 ) <i>AND ! THISFORM.lAborted</i>
   .
   .
   .
ENDDO
</b>

The user clicks "Start" to begin the backup.

The caption on the "Start" button changes to "Cancel"

When the "Cancel" button is clicked, I set THISFORM.lAborted TO .T. but the loop doesn't exit...

What am I missing here??

TIA
