Problem Statement

Move the cursor to column   3,   row   6,   and display the word   "Hello"   (without the quotes),   so that the letter   H   is in column   3   on row   6.

Let's start with the solution:

procedure main()
    writes(CUP(6,3), "Hello")
end

procedure CUP(i,j)
    writes("\^[[",i,";",j,"H")
    return
end
