Hello,
In the header window I have to print data in box for that I put command
/: BOX HEIGHT '2.6' CM WIDTH '13.5' CM FRAME 10 TW
to get the box around the entire window ,this part works
/:BOX YPOS '0.4' CM WIDTH '13.5' CM FRAME 10 TW
This is to get one more horizontal line just 0.4 cm below the upper border of the box
but it prints two lines one below the upper border of the box and the other below
lower border of the box
