    ASSIGN rec:WIDTH-CHARS IN FRAME sz-frame =
                 RANDOM(1, FRAME sz-frame:WIDTH-CHARS - 3) 
           rec:HEIGHT-CHARS = RANDOM(1, FRAME sz-frame:HEIGHT-CHARS - 2)
           FRAME sz-frame:TITLE =  "The rectangle is " +
                 STRING(rec:WIDTH-CHARS) + " by " +
                 STRING(rec:HEIGHT-CHARS).ENABLE rec WITH FRAME sz-frame.

ENABLE b_size b_quit WITH FRAME butt-frame.

WAIT-FOR CHOOSE OF b_quit IN FRAME butt-frame. 
Notes

Progress supports fractional character units. Therefore, if you express dimensions in characters, the width and height values can include up to two decimal places.

For SpeedScript, the PIXEL options are not valid.
