WAIT command does not run in rep loop

[totalolage]

Code:

Copy      Help

RECT r; r.left=292; r.top=433; r.right=641; r.bottom=559;
rep
    out "starting watch"
    wait -1 -S "" rs r
    out "change occured"

(rs is declared correctly)

outputs:
starting watch
*screen change occurs*
change occured
starting watch

then no matter how much the screen region changes, no change is detected.

Move the first line into the loop. Because scan modifies the RECT variable.
