I want to be able to stop my program during a while loop and have tried the following but it did not work.

llgo = .t.
ON KEY LABEL CTRL+HOME llgo = .f.
do while !eof() and llgo = .t.
.
.
code.........
.
.
skip
enddo

Does anyone know what I'm doing wrong. Pressing the ctrl+home key
does not me out of the while loop.

TIA,
Dave
