You have to specify the first and the second (diagonally opposite) corner of the rectangle.
Assuming you want a border frame 5mm within an A4 size sheet the input then would be
rec Enter 0,0 Enter 287,200 Enter.

Or better, first draw a frame with the size of the size of the sheet first (this makes it easier for correct placement when printing) with  rec Enter  0,0 Enter 297,210 Enter
and then draw the inner frame with  rec Enter  5,5 Enter 292,205 Enter
