0020 REM @MENU provides a menu structure for program selection.
: REM Multiple levels of menu can be set up with each successive screen
: REM displaying the next menu node. Node information is overlayed in at
0025 REM lines 9000-9999; each node is saved as a separate program file ('24).
: REM Access to the root node is always available with RESET & LOADRUN if
: REM the progam START is this program or loads in this program.
: REM
0030 REM @MENU is loaded from a program (eg START) that sets $PSTAT=" ".
: REM $PSTAT indicates which node is to be loaded (if " ", the root node).
: REM @MENU sets $PSTAT=node-name when a program is selected, so that the
0035 REM program can return to this menu node by overlaying in @MENU.
