The tutorial program mf_example.c builds a memory file using strings from a text file. The memory file is then displayed in a window, and control is passed over for interactive viewing. Scroll bars have been added to the window for referencing the position of the viewed area within the memory file. Sorting is also performed on the memory file contents. You should read, compile, link, and run mf_example.c to see how these operations work.
