12. manipulation of output results Chapter 3 of this Manual provides a basic explanation of MINEWALL s handling of these three steps and you should carefully review Chapter 3 while running MINEW ALL before continuing here Chapter 4 provides a detailed discussion of important terminology and the manner in which a user moves through MINEWALL and you should again carefully review Chapter 4 before continuing here The aforementioned three steps can be depicted in a flowchart graphically showing each step divided into subtasks for simulations of open pits and underground workings Figure 5 1 Each of the subtasks corresponds to a selection from the Main Menu which was discussed in Chapter 3 The remainder of this Chapter contains detailed descriptions and helpful hints for each of the subtasks selections 5 1 On line and Stand alone Help Facilities When any form or spreadsheet is showing you can obtain on line help by pressing the Help command button if one is showing or by pressing F1 if a Help button is not showing Help can also be accessed from the Main Menu under the Information Submenu Figure 3 4 Help displays a form through which you can browse with the mouse or keyboard as explained in Chapter 4 MINEWALL s on line help is hypertext which means that you can jump from one topic to another by selecting the links surrounded by triangles such as Exit MINEWALL Consequently you should locate such links by browsing through a he
